[PATCH v1] dt-bindings: rtc: mpfs-rtc: permit resets
From: Conor Dooley
Date: Tue Mar 03 2026 - 11:43:23 EST
From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
The RTC on mpfs and pic64gx has a reset pin, but until now this has been
undocumented because platform firmware takes the RTC 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.
