pinctrl: mediatek: Drop bogus slew rate register range for MT8192

2024-02-07T10:47:49+00:00

The MT8192 does not support configuring pin slew rate. This is evident
from both the datasheet, and the fact that the driver points the slew
rate register range at the GPIO direction register range.

Drop the bogus setting.

pinctrl: mediatek: mt7981: add additional emmc groups

2024-01-27T23:52:31+00:00

Add new emmc groups in the pinctrl driver for the
MediaTek MT7981 SoC:
* emmc reset, with pin 15.
* emmc 4-bit bus-width, with pins 16 to 19, and 24 to 25.
* emmc 8-bit bus-width, with pins 16 to 25.

The existing emmc_45 group is kept for legacy reasons, even
if this is the union of emmc_reset and emmc_8 groups.

pinctrl: mediatek: Convert to use grp member

2023-12-11T23:47:52+00:00

Convert drivers to use grp member embedded in struct group_desc,
because other members will be removed to avoid duplication and
desynchronisation of the generic pin group description.

Since pm.h provides a helper for system no-IRQ PM callbacks,
switch the driver to use it instead of open coded variant.
