Simple-Card:
|
||||
|
||||
Simple-Card specifies audio DAI connections of SoC <-> codec.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : "simple-audio-card"
|
||||
|
||||
Optional properties:
|
||||
|
||||
- simple-audio-card,name : User specified audio sound card name, one string
|
||||
property.
|
||||
- simple-audio-card,widgets : Please refer to widgets.txt.
|
||||
- simple-audio-card,routing : A list of the connections between audio components.
|
||||
Each entry is a pair of strings, the first being the
|
||||
connection's sink, the second being the connection's
|
||||
source.
|
||||
- simple-audio-card,mclk-fs : Multiplication factor between stream rate and codec
|
||||
mclk. When defined, mclk-fs property defined in
|
||||
dai-link sub nodes are ignored.
|
||||
- simple-audio-card,hp-det-gpio : Reference to GPIO that signals when
|
||||
headphones are attached.
|
||||
- simple-audio-card,mic-det-gpio : Reference to GPIO that signals when
|
||||
a microphone is attached.
|
||||
- simple-audio-card,aux-devs : List of phandles pointing to auxiliary devices, such
|
||||
as amplifiers, to be added to the sound card.
|
||||
- simple-audio-card,pin-switches : List of strings containing the widget names for
|
||||
which pin switches must be created.
|
||||
|
||||
Optional subnodes:
|
||||
|
||||
- simple-audio-card,dai-link : Container for dai-link level
|
||||
properties and the CPU and CODEC
|
||||
sub-nodes. This container may be
|
||||
omitted when the card has only one
|
||||
DAI link. See the examples and the
|
||||
section below.
|
||||
|
||||
Dai-link subnode properties and subnodes:
|
||||
|
||||
If dai-link subnode is omitted and the subnode properties are directly
|
||||
under "sound"-node the subnode property and subnode names have to be
|
||||
prefixed with "simple-audio-card,"-prefix.
|
||||
|
||||
Required dai-link subnodes:
|
||||
|
||||
- cpu : CPU sub-node
|
||||
- codec : CODEC sub-node
|
||||
|
||||
Optional dai-link subnode properties:
|
||||
|
||||
- format : CPU/CODEC common audio format.
|
||||
"i2s", "right_j", "left_j" , "dsp_a"
|
||||
"dsp_b", "ac97", "pdm", "msb", "lsb"
|
||||
- frame-master : Indicates dai-link frame master.
|
||||
phandle to a cpu or codec subnode.
|
||||
- bitclock-master : Indicates dai-link bit clock master.
|
||||
phandle to a cpu or codec subnode.
|
||||
- bitclock-inversion : bool property. Add this if the
|
||||
dai-link uses bit clock inversion.
|
||||
- frame-inversion : bool property. Add this if the
|
||||
dai-link uses frame clock inversion.
|
||||
- mclk-fs : Multiplication factor between stream
|
||||
rate and codec mclk, applied only for
|
||||
the dai-link.
|
||||
|
||||
For backward compatibility the frame-master and bitclock-master
|
||||
properties can be used as booleans in codec subnode to indicate if the
|
||||
codec is the dai-link frame or bit clock master. In this case there
|
||||
should be no dai-link node, the same properties should not be present
|
||||
at sound-node level, and the bitclock-inversion and frame-inversion
|
||||
properties should also be placed in the codec node if needed.
|
||||
|
||||
Required CPU/CODEC subnodes properties:
|
||||
|
||||
- sound-dai : phandle and port of CPU/CODEC
|
||||
|
||||
Optional CPU/CODEC subnodes properties:
|
||||
|
||||
- dai-tdm-slot-num : Please refer to tdm-slot.txt.
|
||||
- dai-tdm-slot-width : Please refer to tdm-slot.txt.
|
||||
- clocks / system-clock-frequency : specify subnode's clock if needed.
|
||||
it can be specified via "clocks" if system has
|
||||
clock node (= common clock), or "system-clock-frequency"
|
||||
(if system doens't support common clock)
|
||||
If a clock is specified, it is
|
||||
enabled with clk_prepare_enable()
|
||||
in dai startup() and disabled with
|
||||
clk_disable_unprepare() in dai
|
||||
shutdown().
|
||||
If a clock is specified and a
|
||||
multiplication factor is given with
|
||||
mclk-fs, the clock will be set to the
|
||||
calculated mclk frequency when the
|
||||
stream starts.
|
||||
- system-clock-direction-out : specifies clock direction as 'out' on
|
||||
initialization. It is useful for some aCPUs with
|
||||
fixed clocks.
