Commit Message

Icenowy Zheng July 13, 2019, 3:46 a.m. UTC 
Introduce the GPIO pins that is only available on V3 (not on V3s) to the
V3s pinctrl driver.

Signed-off-by: Icenowy Zheng <icenowy@aosc.io>

Changes in v4:
- Removed bogus alignment change.

Changes in v3:
- Fixed code alignment.
- Fixed LVDS function number.

Changes in v2:
- Dropped the driver rename patch and apply the changes directly on V3s
  driver.
