Subject: [PATCH 0/2] Apple M1 pinctrl DT bindings

This small series adds bindings for the pin and GPIO controller found
on the Apple M1 SoC.

At this point, the primary consumer for these bindings is U-Boot.
With the help of these bindings U-Boot can bring up the PCIe root
complex into a state where the OS use it without having to deal with
the GPIO pins.  A Linux driver may be implemented later to support
power management and/or other devices that need GPIO control.  Since
the binding is based on standard pinmux node bindings this should be
relatively easy.
