[PATCH 0/3] Enable audio for J784S4-EVM platform

[Jayesh Choudhary]

Hello All,

These three patches enable audio on J784S4-EVM platform.
- First patch adds the McASP nodes.
- Second patch adds the audio_refclk1 node that is required
  to configure the CTRL_MMR register for the external clock
- Third patch enables the analog audio

For audio to work, the ti-dm firmware that should be picked
for uboot is now publically available and will be shortly
merged to the ti-linux-firmware branch:
<https://git.ti.com/cgit/processor-firmware/ti-linux-firmware/tree/ti-dm/j784s4/ipc_echo_testb_mcu1_0_release_strip.xer5f?h=ti-linux-firmware-next>

For testing, ~/.asoundrc file was created in root partition
which can be seen in the test logs:
<https://gist.github.com/Jayesh2000/3ca38cbac2f37842b1010af79dfe9b4c>

[PATCH 1/3] arm64: dts: ti: k3-j784s4-main: Add McASP nodes

[Jayesh Choudhary]

Add McASP 0-4 instances and keep them disabled as several required
properties are missing as they are board specific.

[PATCH 2/3] arm64: dts: ti: k3-j784s4-main: Add audio_refclk node

[Jayesh Choudhary]

On J784S4 SoC, the AUDIO_REFCLK1 can be used as input to external
peripherals when configured through CTRL_MMR.
Add audio_refclk1 node which would be used as system clock for
audio codec PCM3168A.

[PATCH 3/3] arm64: dts: ti: k3-j784s4-evm: Enable analog audio support

[Jayesh Choudhary]

The audio support on J784S4-EVM is using PCM3168A[0] codec
connected to McASP0 serializers.

- Add the nodes for sound-card, audio codec, MAIN_I2C3 and
  McASP0.
- Add pinmux for I2C3, McASP0 and AUDIO_EXT_REFCLK1.
- Add necessary GPIO hogs to route the MAIN_I2C3 lines and
  McASP serializer.
- Add idle-state as 1 in mux1 to route McASP clock signals.

Does this break CAN instances already enabled in the dts? If you
consider making this a overlay as defaults seem to be set for CAN

This does not break CAN.
The only issue was with p14-hog that was being used by can-3 instance
as mux-gpio and hogging it here was making the resource busy for can.
That I have handled with the idle-state in the gpio mux itself.
