[PATCH v5 8/8] arm64: dts: apple: Enable DockChannel HID on M2 and M3 laptops
From: Michael Reeves via B4 Relay
Date: Sun Nov 08 2026 - 02:28:05 EST
From: Michael Reeves <michael.reeves077@xxxxxxxxx>
Enable the MTP mailbox, DART, DockChannel mailbox, and HID transport on
the M2 and M3 laptop device trees using this internal input path.
Add a keyboard alias and enable DockChannel HID on each machine so the
transport can expose the internal keyboard.
