This is a note to let you know that I've just added the patch titled ARM: dts: stm32: Fix audio routing on STM32MP15xx DHCOM PDK2 to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-dts-stm32-fix-audio-routing-on-stm32mp15xx-dhcom.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 06a3619ceb95a39a32313cea09f687b327f73cbc Author: Marek Vasut <marex@xxxxxxx> Date: Tue Jun 6 20:01:12 2023 +0200 ARM: dts: stm32: Fix audio routing on STM32MP15xx DHCOM PDK2 [ Upstream commit e3f2778b1b6ced649bffdc7cbb05b80bb92f2108 ] The audio routing flow is not correct, the flow should be from source (second element in the pair) to sink (first element in the pair). The flow now is from "HP_OUT" to "Playback", where "Playback" is source and "HP_OUT" is sink, i.e. the direction is swapped and there is no direct link between the two either. Fill in the correct routing, where "HP_OUT" supplies the "Headphone Jack", "Line In Jack" supplies "LINE_IN" input, "Microphone Jack" supplies "MIC_IN" input and "Mic Bias" supplies "Microphone Jack".
