From: Balsam CHIHI <bchihi@baylibre.com>

On MT8365, the SET/CLR of the mode is broken and some pins won't set or clear the modes correctly.
To fix this issue, we add a specific callback mt8365_set_clr_mode() for this specific SoC.
This callback uses the main R/W register to read/update/write the modes instead of using the SET/CLR register.

This is the original patch series proposed by Fabien Parent <fparent@baylibre.com>.

Patches applied, no need to resend for small issues.

Sorry for taking so long, I wanted some feedback from the Mediatek
maintainers but haven't heard anything, so I just applied them.

Hi Linus,

I'm sorry for the delay.
Thank you very much.

Best regards,

nit: subject of cover letter should also include "pinctrl: mediatek:"
prefix.  Also note that you're missing the word "PATCH" in all of the
subjects.

Tip: If you use `git format-patch`, you can just pass `-v2` on the
cmdline and it will create the prefixes for you automatically.
