From b678676b7a0ab65ad5b4278505d6bcf706e53230 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Tue, 3 Mar 2026 16:33:12 +0000 Subject: [PATCH] dt-bindings: gpio: mpfs-gpio: permit resets Both CoreGPIO and the hardened versions of it on mpfs and pic64gx have a reset pin. For the former, usually this is wired to a common fabric reset not managed by software and for the latter two the platform firmware takes them out of reset on first-party boards (or those using modified versions of the vendor firmware), but not all boards may take this approach. Permit providing a reset in devicetree for Linux, or other devicetree-consuming software, to use.
