Kevin Hilman 9c65441ec8 pinctrl/meson: enable building as modules
Enable pinctrl drivers for 64-bit Amlogic SoCs to be built as modules.

The default is still built-in, this only adds the option of building
as modules.

Qianggui Song fd42296407 pinctrl: meson: add a new callback for SoCs fixup
In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:

Since m8-axg share the same ao fixup, make a common function
meson8_aobus_parse_dt_extra to do the job.

Yixun Lan 29ae0952e8 pinctrl: meson-g12a: add pinctrl driver support
Add the pinctrl driver for Meson-G12A SoC which share the similar IP as
the previous Meson-AXG SoC, both use same pinmux ops (register layout).
A new driver is needed here due to the differences in the pins.

Starting from Meson-AXG SoC, the pinctrl controller block use 4
continues register bits to specific the pin mux function, while comparing
to old generation SoC which using variable length register bits for
the pin mux definition. The new design greatly simplify the software model.

For the detail example, one 32bit register can be divided into 8 parts,
each has 4 bits whose value start from 0 - 7, each can describe one pin,
the value 0 is always devoted to GPIO function, while 1 - 7 devoted to
the mux pin function.

Please note, the GPIOE is actually located at AO (always on) bank.
