This is a note to let you know that I've just added the patch titled ARM: dts: imx7: Use audio_mclk_post_div instead audio_mclk_root_clk to the 5.4-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-imx7-use-audio_mclk_post_div-instead-audio_mclk_root_clk.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 4cb7df64c732b2b9918424095c11660c2a8c4a33 Mon Sep 17 00:00:00 2001 From: Abel Vesa <abel.vesa@xxxxxxx> Date: Thu, 27 Jan 2022 16:10:51 +0200 Subject: ARM: dts: imx7: Use audio_mclk_post_div instead audio_mclk_root_clk From: Abel Vesa <abel.vesa@xxxxxxx> commit 4cb7df64c732b2b9918424095c11660c2a8c4a33 upstream. The audio_mclk_root_clk was added as a gate with the CCGR121 (0x4790), but according to the reference manual, there is no such gate. Moreover, the consumer driver of the mentioned clock might gate it and leave the ECSPI2 (the true owner of that gate) hanging. So lets use the audio_mclk_post_div, which is the parent.
