[PATCH v5 0/3] pinctrl: meson-a1: add pinctrl driver

[Qianggui Song]

This patchset adds Pin controller driver support for Meson-A1 Soc
which shares the same register layout of pinmux with previous
Meson-G12A, however there is difference for gpio and pin config
registers in A1.

Note that since dt-binding patch has been removed from this patch set,
compiling need header file in patch 1 of [3].

Changes since v4 at [3]
 - remove dt-binding patch for it can be merged first according to
 Linus Walleij's suggestion.
 - make SoCs before g12a share the same aobus dt paser function
 - make A1 dt paser function also as common part for later chip will
 re-use this definition.
 - modify meson_map_resource return value

Changes since v3 at [2]
 - separate ao fixup from meson_pinctrl_parse_dt
 - provide ao extra dt parse callback for each SoC

Changes since v2 at [1]:
 - make dt parser callback as a separate patch

Changes since v1 at [0]:
 - collect Reviewed-by
 - modify commit log
 - add an extra dt parser function for a1
