Subject: [PATCH v3 0/2] Apple M1 pinctrl DT bindings
Date: Thu, 20 May 2021 19:13:05 +0200 [thread overview]
Message-ID: <20210520171310.772-1-mark.kettenis@xs4all.nl> (raw)
From: Mark Kettenis <kettenis@openbsd.org>
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.
Changelog:
v2: - Fix typo in DT schema
v3: - Add description for interrupts property
