Subject: pinctrl: sunxi: Libraryse the driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2284ba6b7d8310d09f3a0a5d81669632532ec26c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: sunxi: Libraryse the driver

This will allow to have multiple drivers using the same core code, and
eventually, retire pinctrl-sunxi-pins.h
