Subject: [v2, 0/2] Fix broken SET/CLR mode of a certain number of pins for MediaTek MT8385 SoC

From: Balsam CHIHI <bchihi@...libre.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@...libre.com>.
