Subject: [PATCH v3 0/2] pinctrl: meson: prepare for new SoC

The goal of this patchset is to prepare meson pinctrl driver to
add a new meson SoC support. This new SoC will share the same pinconf/gpio
registers but the pinmux part will be slightly different.

First patch allows to compile and ship only the necessary pinctrl drivers,
depending on the architecture and configuration needs. This should save
a bit of memory.

Second patch provide a way to deal with a different pinmux scheme, while
reusing most of the meson pinctrl driver.

Linus, FYI, this series has been rebased on your devel branch

Change since v2: [1]
* Fix compilation issue on i386 reported by kbuild test robot

Change since v1: [0]
* Use of_device_get_match_data() in patch
* Change pmx naming scheme for the SoC parts
