Add a new pinctrl driver for Amlogic A4 SoCs which share
the same register layout as the previous Amlogic S4.

Hi,

a few nitpicks below.

...

I think that struct meson_pmx_group could be const.
(same for a4_aobus_groups above)

> +	GPIO_GROUP(GPIOE_0),

I think that struct meson_pmx_func could be const.
(a4_aobus_functions above as well)

I think that both struct meson_bank could be const.

Usually, there is no extra "," after a terinator item.

Hi Christophe,
     Thanks for your advice. It will be added in the next version.
