[PATCH 0/2] Apple M1 pinctrl DT bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mark Kettenis <kettenis@xxxxxxxxxxx>

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

  dt-bindings: pinctrl: Add DT bindings for apple,pinctrl
  arm64: apple: Add pinctrl nodes
