This is a note to let you know that I've just added the patch titled mmc: renesas_sdhi: better reset from HS400 mode to the 5.10-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: mmc-renesas_sdhi-better-reset-from-hs400-mode.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c904e27acec86dbbddb575b2ca7cf8ee399d2f64 Author: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx> Date: Sun Nov 20 12:34:55 2022 +0100 mmc: renesas_sdhi: better reset from HS400 mode [ Upstream commit 0da69dd2155019ed4c444ede0e79ce7a4a6af627 ] Up to now, HS400 adjustment mode was only disabled on soft reset when a calibration table was in use. It is safer, though, to disable it as soon as the instance has an adjustment related quirk set, i.e. bad taps or a calibration table.
