This is a driver for the pinmux and GPIO controller available in
Amlogic Meson SoCs. It currently supports only Meson8, however the
common code should be generic enough to work also for other SoCs after
having defined the proper set of functions and groups.
GPIO interrupts are not supported at the moment due to lack of
documentation.

All Tegra GPIOs are named after the GPIO bank and GPIO number within
the bank. Define a macro to calculate the GPIO ID based on those
parameters. Make the macro available via all Tegra .dtsip files.

Many GPIO device tree bindings use the same flags. Create a header to
define those.
