Subject: [PATCH v6 10/12] pinctrl: Ingenic: Add pinctrl driver for JZ4755.
Add support for probing the pinctrl-ingenic driver on the
JZ4755 SoC from Ingenic.
Signed-off-by: 周琰杰 (Zhou Yanjie) <zhouyanjie@...yeetech.com>
Reviewed-by: Andy Shevchenko <andy.shevchenko@...il.com>

Notes:
v3:
New patch.
v3->v4:
1.Split LCD pins into several groups.
2.Drop "lcd-no-pins" which is pointless.
v4->v5:
No change.
v5->v6:
Add Paul Cercueil's Reviewed-by.
