2026-04-03T14:56:57+00:00

Add the OLPC XO-1 RTC compatible string to the trivial-rtc schema instead of creating a standalone binding file, as it only requires a compatible property with no additional configuration.

dt-bindings: rtc: mpfs-rtc: permit resets

2026-03-12T14:33:59+00:00

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.
