+/*! \page topology ALSA Topology Interface
+ *
+ * The topology interface allows developers to define DSP topologies in a text
+ * file format and to convert the text topology to a binary topology
+ * representation that can be understood by the kernel. The topology core
+ * currently recognises the following object types :-
+ *
+ *  * Controls (mixer, enumerated and byte) including TLV data.
+ *  * PCMs (Front End DAI & DAI link)
+ *  * DAPM widgets
+ *  * DAPM graph elements.
+ *  * Physical DAI & DAI links
+ *  * Private data for each object type.
+ *  * Manifest (containing count of each object type)
+ *
+ * <h3>Topology File Format</h3>
+ *
+ * The topology text format uses the standard ALSA configuration file format to
+ * describe each topology object type. This allows topology objects to include
+ * other topology objects as part of their definition. i.e. a TLV data object
+ * can be shared amongst many control objects that use the same TLV data.
+ *
+ *
+ * <h4>Controls</h4>
+ * Topology audio controls can belong to three different types :-
+ *   * Mixer control
+ *   * Enumerated control
+ *   * Byte control
+ *
+ * Each control type can contain TLV data, private data, operations and also
+ * belong to widget objects.<br>
+ *
+ * <h5>Control Operations</h5>
+ * Driver Kcontrol callback info(), get() and put() operations are mapped with
+ * the CTL ops section in topology configuration files. The ctl ops section can
+ * assign operations using the standard names (listed below) for the standard
+ * kcontrol types or use ID numbers (>256) to map to bespoke driver controls.<br>
+ *
+ * <pre>
+ *
+ *	ops."ctl" {
+ *		info "volsw"
+ *		get "257"
+ *		put "257"
+ *	}
+ *
+ * </pre>
+ *
+ * This mapping shows info() using the standard "volsw" info callback whilst
+ * the get() and put() are mapped to bespoke driver callbacks. <br>
+ *
+ * The Standard operations names for control get(), put() and info calls
+ * are :-
+ *  * volsw
+ *  * volsw_sx
+ *  * volsw_xr_sx
+ *  * enum
+ *  * bytes
+ *  * enum_value
+ *  * range
+ *  * strobe
+ *
+* <h5>Control Access</h5>
+ * Controls access can be specified using the "access" section. If no "access"
+ * section is defined then default RW access flags are set for normal and TLV
+ * controls.
+ *
+ * <pre>
+ *	access [
+ *		read
+ *		write
+ *		tlv_command
+ *	]
+ * </pre>
+ *
+ * The standard access flags are as follows :-
+ *  * read
+ *  * write
+ *  * read_write
+ *  * volatile
+ *  * timestamp
+ *  * tlv_read
+ *  * tlv_write
+ *  * tlv_read_write
+ *  * tlv_command
+ *  * inactive
+ *  * lock
+ *  * owner
+ *  * tlv_callback
+ *  * user
+ *
+ * <h5>Control TLV Data</h5>
+ * Controls can also use TLV data to represent dB information. This can be done
+ * by defining a TLV section and using the TLV section within the control.
+ * The TLV data for DBScale types are defined as follows :-
+ *
+ * <pre>
+ *	scale {
+ *		min "-9000"
+ *		step "300"
+ *		mute "1"
+ *	}
+ * </pre>
+ *
+ * Where the meanings and values for min, step and mute are exactly the same
+ * as defined in driver code.
+ *
+ * <h5>Control Channel Mapping</h5>
+ * Controls can also specify which channels they are mapped with. This is useful
+ * for userspace as it allows applications to determine the correct control
+ * channel for Left and Right etc. Channel maps are defined as follows :-
+ *
+ * <pre>
+ *	channel."name" {
+ *		reg "0"
+ *		shift "0"
+ *	}
+ * </pre>
+ *
+ * The channel map reg is the register offset for the control, shift is the
+ * bit shift within the register for the channel and the section name is the
+ * channel name and can be one of the following :-
+ *
+ * <pre>
+ *  * mono		# mono stream
+ *  * fl 		# front left
+ *  * fr		# front right
+ *  * rl		# rear left
+ *  * rr		# rear right
+ *  * fc		# front center
+ *  * lfe		# LFE
+ *  * sl		# side left
+ *  * sr		# side right
+ *  * rc		# rear center
+ *  * flc		# front left center
+ *  * frc		# front right center
+ *  * rlc		# rear left center
+ *  * rrc		# rear right center
+ *  * flw		# front left wide
+ *  * frw		# front right wide
+ *  * flh		# front left high
+ *  * fch		# front center high
+ *  * frh		# front right high
+ *  * tc		# top center
+ *  * tfl		# top front left
+ *  * tfr		# top front right
+ *  * tfc		# top front center
+ *  * trl		# top rear left
+ *  * trr		# top rear right
+ *  * trc		# top rear center
+ *  * tflc		# top front left center
+ *  * tfrc		# top front right center
+ *  * tsl		# top side left
+ *  * tsr		# top side right
+ *  * llfe		# left LFE
+ *  * rlfe		# right LFE
+ *  * bc		# bottom center
+ *  * blc		# bottom left center
+ *  * brc		# bottom right center
+ * </pre>
+ *
+ *  <h5>Control Private Data</h5>
+ * Controls can also have private data. This can be done by defining a private
+ * data section and including the section within the control. The private data
+ * section is defined as follows :-
+ *
+ * <pre>
+ * SectionData."pdata for EQU1" {
+ *	file "/path/to/file"
+ *	bytes "0x12,0x34,0x56,0x78"
+ *	shorts "0x1122,0x3344,0x5566,0x7788"
+ *	words "0xaabbccdd,0x11223344,0x66aa77bb,0xefef1234"
+ *	tuples "section id of the vendor tuples"
+ * };
+ * </pre>
+ * The file, bytes, shorts, words and tuples keywords are all mutually
+ * exclusive as the private data should only be taken from one source.
+ * The private data can either be read from a separate file or defined in
+ * the topology file using the bytes, shorts, words or tuples keywords.
+ * The keyword tuples is to define vendor specific tuples. Please refer to
+ * section Vendor Tokens and Vendor tuples.
+ *
+ * <h5>How to define an element with private data</h5>
+ * An element can refer to a single data section or multiple data
+ * sections.
+ *
+ * <h6>To refer to a single data section:</h6>
+ * <pre>
+ * Sectionxxx."element name" {
+ *    ...
+ *	data "name of data section"		# optional private data
+ * }
+ * </pre>
+ *
+ * <h6>To refer to multiple data sections:</h6>
+ * <pre>
+ * Sectionxxx."element name" {
+ *	...
+ *	data [						# optional private data
+ *		"name of 1st data section"
+ *		"name of 2nd data section"
+ *		...
+ *	]
+ * }
+ * </pre>
+ * And data of these sections will be merged in the same order as they are
+ * in the list, as the element's private data for kernel.
+ *
+ * </pre>
+ *
+ *  <h6>Vendor Tokens</h6>
+ * A vendor token list is defined as a new section. Each token element is
+ * a pair of string ID and integer value. And both the ID and value are
+ * vendor-specific.
+ *
+ * <pre>
+ * SectionVendorTokens."id of the vendor tokens" {
+ *	comment "optional comments"
+ *	VENDOR_TOKEN_ID1 "1"
+ *	VENDOR_TOKEN_ID2 "2"
+ *	VENDOR_TOKEN_ID3 "3"
+ *	...
+ * }
+ * </pre>
+ *
+ *  <h6>Vendor Tuples</h6>
+ * Vendor tuples are defined as a new section. It contains a reference to
+ * a vendor token list and several tuple arrays.
+ * All arrays share a vendor token list, defined by the tokens keyword.
+ * Each tuple array is for a specific type, defined by the string following
+ * the tuples keyword. Supported types are: string, uuid, bool, byte,
+ * short and word.
+ *
+ * <pre>
+ * SectionVendorTuples."id of the vendor tuples" {
+ *	tokens "id of the vendor tokens"
+ *
+ *	tuples."string" {
+ *		VENDOR_TOKEN_ID1 "character string"
+ *		...
+ *	}
+ *
+ *	tuples."uuid" {			# 16 characters separated by commas
+ *		VENDOR_TOKEN_ID2 "0x01,0x02,...,0x0f"
+ *		...
+ *	}
+ *
+ *	tuples."bool" {
+ *		VENDOR_TOKEN_ID3 "true/false"
+ *		...
+ *	}
+ *
+ *	tuples."byte" {
+ *		VENDOR_TOKEN_ID4 "0x11"
+ *		VENDOR_TOKEN_ID5 "0x22"
+ *		...
+ *	}
+ *
+ *	tuples."short" {
+ *		VENDOR_TOKEN_ID6 "0x1122"
+ *		VENDOR_TOKEN_ID7 "0x3344"
+ *		...
+ *	}
+ *
+ *	tuples."word" {
+ *		VENDOR_TOKEN_ID8 "0x11223344"
+ *		VENDOR_TOKEN_ID9 "0x55667788"
+ *		...
+ *	}
+ * }
+ * </pre>
+ * To define multiple vendor tuples of same type, please append some
+ * characters after the type string ("string", "uuid", "bool", "byte", "short"
+ * or "word"), to avoid ID duplication in the SectionVendorTuples.<br>
+ * The parser will check the first few characters in ID to get the tuple type.
+ * Here is an example:
+ * <pre>
+ * SectionVendorTuples."id of the vendor tuples" {
+ *    ...
+ *	tuples."word.module0" {
+ *		VENDOR_TOKEN_PARAM_ID1 "0x00112233"
+ *		VENDOR_TOKEN_PARAM_ID2 "0x44556677"
+ *		...
+ *	}
+ *
+ *	tuples."word.module2" {
+ *		VENDOR_TOKEN_PARAM_ID1 "0x11223344"
+ *		VENDOR_TOKEN_PARAM_ID2 "0x55667788"
+ *		...
+ *	}
+ *	...
+ * }
+ *
+ * </pre>
+ *
+ * <h5>Mixer Controls</h5>
+ * A mixer control is defined as a new section that can include channel mapping,
+ * TLV data, callback operations and private data. The mixer section also
+ * includes a few other config options that are shown here :-
+ *
+ * <pre>
+ * SectionControlMixer."mixer name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	max "32"			# Max control value
+ *	invert "0"			# Whether control values are inverted
+ *
+ *	tlv "tld_data"			# optional TLV data
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ * </pre>
+ *
+ * The section name is used to define the mixer name. The index number can be
+ * used to identify topology objects groups. This allows driver operations on
+ * objects with index number N and can be used to add/remove pipelines of
+ * objects whilst other objects are unaffected.
+ *
+ * <h5>Byte Controls</h5>
+ * A byte control is defined as a new section that can include channel mapping,
+ * TLV data, callback operations and private data. The bytes section also
+ * includes a few other config options that are shown here :-
+ *
+ * <pre>
+ * SectionControlBytes."name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	base "0"			# Register base
+ *	num_regs "16"			# Number of registers
+ *	mask "0xff"			# Mask
+ *	max "255"			# Maximum value
+ *
+ *	tlv "tld_data"			# optional TLV data
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ * </pre>
+ *
+ * <h5>Enumerated Controls</h5>
+ * A enumerated control is defined as a new section (like mixer and byte) that
+ * can include channel mapping, callback operations, private data and
+ * text strings to represent the enumerated control options.<br>
+ *
+ * The text strings for the enumerated controls are defined in a separate
+ * section as follows :-
+ *
+ * <pre>
+ * SectionText."name" {
+ *
+ *		Values [
+ *			"value1"
+ *			"value2"
+			"value3"
+ *		]
+ * }
+ * </pre>
+ *
+ * All the enumerated text values are listed in the values list.<br>
+ * The enumerated control is similar to the other controls and defined as
+ * follows :-
+ *
+ * <pre>
+ * SectionControlMixer."name" {
+ *	comment "optional comments"
+ *
+ *	index "1"			# Index number
+ *
+ *	texts "EQU1"			# Enumerated text items
+ *
+ *	channel."name" {		# Channel maps
+ *	   ....
+ *	}
+ *
+ *	ops."ctl" {			# Ops callback functions
+ *	   ....
+ *	}
+ *
+ *	data "pdata for mixer1"		# optional private data
+ * }
+ * </pre>
+ *
+ * <h4>DAPM Graph</h4>
+ * DAPM graphs can easily be defined using the topology file. The format is
+ * very similar to the DAPM graph kernel format. :-
+ *
+ * <pre>
+ * SectionGraph."dsp" {
+ *	index "1"			# Index number
+ *
+ *	lines [
+ *		"sink1, control, source1"
+ *		"sink2, , source2"
+ *	]
+ * }
+ * </pre>
+ *
+ * The lines in the graph are defined as a variable size list of sinks,
+ * controls and sources. The control name is optional as some graph lines have
+ * no associated controls. The section name can be used to differentiate the
+ * graph with other graphs, it's not used by the kernel atm.
+ *
+ * <h4>DAPM Widgets</h4>
+ * DAPM widgets are similar to controls in that they can include many other
+ * objects. Widgets can contain private data, mixer controls and enum controls.
+ *
+ * The following widget types are supported and match the driver types :-
+ *
+ *  * input
+ *  * output
+ *  * mux
+ *  * mixer
+ *  * pga
+ *  * out_drv
+ *  * adc
+ *  * dac
+ *  * switch
+ *  * pre
+ *  * post
+ *  * aif_in
+ *  * aif_out
+ *  * dai_in
+ *  * dai_out
+ *  * dai_link
+ *
+ * Widgets are defined as follows :-
+ *
+ * <pre>
+ * SectionWidget."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	type "aif_in"			# Widget type - detailed above
+ *	stream_name "name"		# Stream name
+ *
+ *	no_pm "true"			# No PM control bit.
+ *	reg "20"			# PM bit register offset
+ *	shift "0"			# PM bit register shift
+ *	invert "1			# PM bit is inverted
+ *	subseq "8"			# subsequence number
+ *
+ *	event_type "1"			# DAPM widget event type
+ *	event_flags "1"			# DAPM widget event flags
+ *
+ *	mixer "name"			# Optional Mixer Control
+ *	enum "name"			# Optional Enum Control
+ *
+ *	data "name"			# optional private data
+ * }
+ * </pre>
+ *
+ * The section name is the widget name. The mixer and enum fields are mutually
+ * exclusive and used to include controls into the widget. The index and data
+ * fields are the same for widgets as they are for controls whilst the other
+ * fields map on very closely to the driver widget fields.
+ *
+ * <h5>Widget Private Data</h5>
+ * Widget can have private data. For the format of the private data, please
+ * refer to section Control Private Data.
+ *
+ * <h4>PCM Capabilities</h4>
+ * Topology can also define the PCM capabilities of front end or physical DAIs.
+ * Capabilities can be defined with the following section :-
+ *
+ * <pre>
+ * SectionPCMCapabilities."name" {
+ *
+ *	formats "S24_LE,S16_LE"		# Supported formats
+ *	rate_min "48000"		# Max supported sample rate
+ *	rate_max "48000"		# Min supported sample rate
+ *	channels_min "2"		# Min number of channels
+ *	channels_max "2"		# max number of channels
+ * }
+ * </pre>
+ * The supported formats use the same naming convention as the driver macros.
+ * The PCM capabilities name can be referred to and included by PCM and
+ * physical DAI sections.
+ *
+ * <h4>PCM Configurations</h4>
+ * PCM runtime configurations can be defined for playback and capture stream
+ * directions with the following section  :-
+ *
+ * <pre>
+ * SectionPCMConfig."name" {
+ *
+ *	config."playback" {		# playback config
+ *		format "S16_LE"		# playback format
+ *		rate "48000"		# playback sample rate
+ *		channels "2"		# playback channels
+ *		tdm_slot "0xf"		# playback TDM slot
+ *	}
+ *
+ *	config."capture" {		# capture config
+ *		format "S16_LE"		# capture format
+ *		rate "48000"		# capture sample rate
+ *		channels "2"		# capture channels
+ *		tdm_slot "0xf"		# capture TDM slot
+ *	}
+ * }
+ * </pre>
+ *
+ * The supported formats use the same naming convention as the driver macros.
+ * The PCM configuration name can be referred to and included by PCM and
+ * physical link sections.
+ *
+ * <h4>PCM (Front-end DAI & DAI link) </h4>
+ * PCM sections define the supported capabilities and configurations for
+ * supported playback and capture streams, names and flags for front end
+ * DAI & DAI links. Topology kernel driver will use a PCM object to create
+ * a pair of FE DAI & DAI links.
+ *
+ * <pre>
+ * SectionPCM."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the PCM
+ *
+ *	dai."name of front-end DAI" {
+ *		id "0"		# used for binding to the front-end DAI
+ *	}
+ *
+ *	pcm."playback" {
+ *		capabilities "capabilities1"	# capabilities for playback
+ *
+ *		configs [		# supported configs for playback
+ *			"config1"
+ *			"config2"
+ *		]
+ *	}
+ *
+ *	pcm."capture" {
+ *		capabilities "capabilities2"	# capabilities for capture
+ *
+ *		configs [		# supported configs for capture
+ *			"config1"
+ *			"config2"
+ *			"config3"
+ *		]
+ *	}
+ *
+ *	# Optional boolean flags
+ *	symmetric_rates			"true"
+ *	symmetric_channels		"true"
+ *	symmetric_sample_bits		"false"
+ *
+ *	data "name"			# optional private data
+ * }
+ * </pre>
+ *
+ * <h4>Physical DAI Link Configurations</h4>
+ * The runtime configurations of a physical DAI link can be defined by
+ * SectionLink. <br> Backend DAI links belong to physical links, and can
+ * be configured by either SectionLink or SectionBE, with same syntax.
+ * But SectionBE is deprecated atm since the internal processing is
+ * actually same.
+ *
+ * <pre>
+ * SectionLink."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the link
+ *
+ *	stream_name "name"		# used for binding to the link
+ *
+ *	hw_configs [	# runtime supported HW configurations, optional
+ *		"config1"
+ *		"config2"
+ *		...
+ *	]
+ *
+ *	default_hw_conf_id "1"		#default HW config ID for init
+ *
+ *	# Optional boolean flags
+ *	symmetric_rates			"true"
+ *	symmetric_channels		"false"
+ *	symmetric_sample_bits		"true"
+ *
+ *	data "name"			# optional private data
+ * }
+ * </pre>
+ *
+ * A physical link can refer to multiple runtime supported hardware
+ * configurations, which is defined by SectionHWConfig.
+ *
+ * <pre>
+ * SectionHWConfig."name" {
+ *
+ *	id "1"				# used for binding to the config
+ *	format "I2S"			# physical audio format.
+ *	bclk   "master"			# Platform is master of bit clock
+ *	fsync  "slave"			# Platform is slave of fsync
+ * }
+ * </pre>
+ *
+ * <h4>Physical DAI</h4>
+ * A physical DAI (e.g. backend DAI for DPCM) is defined as a new section
+ * that can include a unique ID, playback and capture stream capabilities,
+ * optional flags, and private data. <br>
+ * Its PCM stream capablities are same as those for PCM objects,
+ * please refer to section 'PCM Capabilities'.
+ *
+ * <pre>
+ * SectionDAI."name" {
+ *
+ *	index "1"			# Index number
+ *
+ *	id "0"				# used for binding to the Backend DAI
+ *
+ *	pcm."playback" {
+ *		capabilities "capabilities1"	# capabilities for playback
+ *	}
+ *
+ *	pcm."capture" {
+ *		capabilities "capabilities2"	# capabilities for capture
+ *	}
+ *
+ *	symmetric_rates "true"			# optional flags
+ *	symmetric_channels "true"
+ *	symmetric_sample_bits "false"
+ *
+ *	data "name"			# optional private data
+ * }
+ * </pre>
+ *
+ * <h4>Manifest Private Data</h4>
+ * Manfiest may have private data. Users need to define a manifest section
+ * and add the references to 1 or multiple data sections. Please refer to
+ * section 'How to define an element with private data'. <br>
+ * And the text conf file can have at most 1 manifest section. <br><br>
+ *
+ * Manifest section is defined as follows :-
+ *
+ * <pre>
+ * SectionManifest"name" {
+ *
+ *	data "name"			# optional private data
+ * }
+ * </pre>
+ *
+ * <h4>Include other files</h4>
+ * Users may include other files in a text conf file via alsaconf syntax
+ * <path/to/configuration-file>. This allows users to define common info
+ * in separate files (e.g. vendor tokens, tuples) and share them for
+ * different platforms, thus save the total size of config files. <br>
+ * Users can also specifiy additional configuraiton directories relative
+ * to "/usr/share/alsa/" to search the included files,  via alsaconf syntax
+ * <searchfdir:/relative-path/to/usr/share/alsa>. <br><br>
+ *
+ * For example, file A and file B are two text conf files for platform X,
+ * they will be installed to /usr/share/alsa/topology/platformx. If we
+ * need file A to include file B, in file A we can add: <br>
+ *
+ * <searchdir:topology/platformx> <br>
+ * <name-of-file-B> <br><br>
+ *
+ * ALSA conf will search and open an included file in the following order
+ * of priority:
+ *  1. directly open the file by its name;
+ *  2. search for the file name in "/usr/share/alsa";
+ *  3. search for the file name in user specified subdirectories under
+ *     "/usr/share/alsa".
+ *
+ * The order of the included files need not to be same as their
+ * dependencies, since the topology library will load them all before
+ * parsing their dependencies. <br>
+ *
+ * The configuration directories defined by a file will only be used to search
+ * the files included by this file.
