Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

NVIDIA Tegra audio complex, with RT5640 CODEC
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-rt5640"
|
|
- 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 RT5640's pins (as documented in its binding), and the jacks
|
|
on the board:
|
|
|
|
* Headphones
|
|
* Speakers
|
|
* Mic Jack
|
|
|
|
- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
|
|
connected to the CODEC.
|
|
- nvidia,audio-codec : The phandle of the RT5640 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
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "nvidia,tegra-audio-rt5640-dalmore",
|
|
"nvidia,tegra-audio-rt5640";
