This patch series try to add pinctrl driver support for
the Meson-G12A SoC.

  The pinctrl driver for Meson-G12A SoC share the similar IP as
the previous Meson-AXG SoC, both use same pinmux ops (register layout).
But, a new driver is needed here due to the differences in the pins.

Changes since v2 at [2]
 - use ${FUNCTION}_${DOMAIN}_${PORT}_${PINFUNC}_${BANK}${PINNUM}
   to rename some pins
 - fix tdm groups
 - explain the similarity of pinmux between AXG and G12A - thanks Martin 
 - collect Rob's Reviewed-by

Changes since v1 at [1]
 - add Martin's Ack, Xingyu's Signed-off
 - squash patch 1,2 (documentation & header file)
 - explain pinctrl IP
 - notice GPIOE located in AO bank
