This RFC series is a work on replacing static platform-specific data in
pinctrl-samsung driver with data dynamically parsed from device tree.
It aims at reducing the SoC-specific part of the driver and thus the
amount of modifications to driver sources when adding support for next
SoCs (like Exynos4x12).
Furthermore, moving definitions of pin banks to device tree will allow
to simplify GPIO and GEINT specification to a format similar to used
previously by gpiolib-based implementation, using a phandle to the bank
and pin index inside the bank, e.g.
gpios = <&gpa1 4 0>;
interrupt-parent = <&gpa1>;
interrupts = <4 0>;
Any comments are welcome.
TODO:
- bindings documentation
- per-bank GPIO and GEINT specification
