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. Signed-off-by: Jean Thomas <jean.thomas@wifirst.fr>

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.
