Subject: Broken Audio on Stable Kernels for i.MX 7 based Boards
Date: Fri, 20 May 2022 13:25:29 +0000	[thread overview]
Message-ID: <536ad55a36d88364299f22782f7c12a6c70c5c11.camel@toradex.com> (raw)

Hello

I noticed today, that commit eccac77ede394 ("clk: imx7d: Remove
audio_mclk_root_clk") was backported to stable kernels. This commit by
itself does break audio functionality on i.MX 7 based boards. [1]

For this to work commit 4cb7df64c73 ("ARM: dts: imx7: Use
audio_mclk_post_div instead audio_mclk_root_clk") is also needed but is
lacking a Fixes: tag, hence it is missing in stable kernels. [2]

I noticed this while merging stable-patches into our downstream-
branches.

@Abel can you confirm my finding?
@Greg could you pull patch [2] into kernels where [1] got merged? 

Thanks,
Philippe
