Initial Apple silicon M3 device trees and dt-bindings

[PATCH 5/9] dt-bindings: pinctrl: apple,pinctrl: Add t8122 compatible

Posted by Janne Grunau 2 weeks ago

The pin controller on the Apple silicon t8122 (M3) SoC is compatible
with the existing driver. Add "apple,t8122-pinctrl" as SoC specific
compatible under "apple,t8103-pinctrl" used by the driver.
