[PATCH v2] dt-bindings: sound: nvidia, tegra-audio: Convert multiple txt bindings to yaml

David Heidelberg david at ixit.cz
Sat Dec 11 23:49:44 CET 2021


Convert Tegra audio complex with the
  * ALC5632
  * MAX98090
  * RT5640
  * RT5677
  * SGTL5000
  * TrimSlice
  * WM8753
  * WM8903
  * WM9712
codec to the YAML format.

Additional changes:
 - added missing HPOUTL to the WM9712 codec.
 - extended rt5677 codec with multiple pins

Reviewed-by: Dmitry Osipenko <digetx at gmail.com>
Signed-off-by: David Heidelberg <david at ixit.cz>

v2:
 - converted from one big schema into the common properties and then references to it
 - few additional changes mentioned in commit message

-NVIDIA Tegra audio complex, with RT5677 CODEC
-
-Required properties:
-- compatible : "nvidia,tegra-audio-rt5677"
-- clocks : Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries:
-  - pll_a
-  - pll_a_out0
-  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
-- nvidia,model : The user-visible name of this sound complex.
-- nvidia,audio-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. Valid names for sources and
-  sinks are the RT5677's pins (as documented in its binding), and the jacks
-  on the board:
-
-  * Headphone
-  * Speaker
-  * Headset Mic
-  * Internal Mic 1
-  * Internal Mic 2
-
-- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
-  connected to the CODEC.
-- nvidia,audio-codec : The phandle of the RT5677 audio codec. This binding
-  assumes that AIF1 on the CODEC is connected to Tegra.
-
-Optional properties:
-- nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in
-- nvidia,hp-en-gpios : The GPIO that enables headphone amplifier
-- nvidia,mic-present-gpios: The GPIO that mic jack is plugged in
-- nvidia,dmic-clk-en-gpios : The GPIO that gates DMIC clock signal

-NVIDIA Tegra audio complex
-
-Required properties:
-- compatible : "nvidia,tegra-audio-wm8903"
-- clocks : Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries:
-  - pll_a
-  - pll_a_out0
-  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
-- nvidia,model : The user-visible name of this sound complex.
-- nvidia,audio-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. Valid names for sources and
-  sinks are the WM8903's pins (documented in the WM8903 binding document),
-  and the jacks on the board:
-
-  * Headphone Jack
-  * Int Spk
-  * Mic Jack
-  * Int Mic
-
-- nvidia,i2s-controller : The phandle of the Tegra I2S1 controller
-- nvidia,audio-codec : The phandle of the WM8903 audio codec
-
-Optional properties:
-- nvidia,spkr-en-gpios : The GPIO that enables the speakers
-- nvidia,hp-mute-gpios : The GPIO that mutes the headphones
-- nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
-- nvidia,int-mic-en-gpios : The GPIO that enables the internal microphone
-- nvidia,ext-mic-en-gpios : The GPIO that enables the external microphone
-- nvidia,headset : The Mic Jack represents state of the headset microphone pin
