Subject: [PATCH v5 1/6] pinctrl: sunxi: v3s: introduce support for V3
Introduce the GPIO pins that is only available on V3 (not on V3s) to the
V3s pinctrl driver.
Signed-off-by: Icenowy Zheng <icenowy@...c.io>
Acked-by: Maxime Ripard <maxime.ripard@...tlin.com>

No changes in v5.
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.
