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> Changelog v1->v2: - Rebase on tag next-20240624 - Add padding in mcasp reg property - Add assigned-clock and assigned-clock-parents property for mcasp for more accurate description - Change mcasp pinmux node name similar to other nodes - Fix typo in k3_clk node and remove unnecessary comments for refclk1 v1 patch: <https://lore.kernel.org/all/20240619095253.290552-1-j-choudhary@xxxxxx/> Jayesh Choudhary (3): arm64: dts: ti: k3-j784s4-main: Add McASP nodes arm64: dts: ti: k3-j784s4-main: Add audio_refclk node arm64: dts: ti: k3-j784s4-evm: Enable analog audio support arch/arm64/boot/dts/ti/k3-j784s4-evm.dts | 111 +++++++++++++++++++++ arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi | 99 ++++++++++++++++++ 2 files changed, 210 insertions(+) -- 2.25.1
