Subject: [PATCH 0/2] Apple M1 pinctrl DT bindings
Date: Sat,  8 May 2021 16:19:54 +0200	[thread overview]
Message-ID: <20210508142000.85116-1-kettenis@openbsd.org> (raw)

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.
