dt-bindings: rtc: add olpc,xo1-rtc to trivial-rtc

2026-04-03T14:56:57Z

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.

The RTC block found in the SC2730 PMIC is compatible with the one found in the SC2731 PMIC. Acked-by: Rob Herring (Arm) Signed-off-by: Otto Pflüger Link: https://patch.msgid.link/20260329-sc27xx-mfd-cells-v3-1-9158dee41f74@abscue.de Signed-off-by: Alexandre Belloni

dt-bindings: rtc: isl12026: convert to YAML schema

2026-03-13T10:09:32Z

Convert the ISL12026 RTC binding from text format to YAML schema. Remove the legacy text binding. The new schema enables dtbs_check validation.

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

2026-03-12T14:33:59Z

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.

dt-bindings: rtc: loongson: Document Loongson-2K0300 compatible

2026-01-30T23:12:32Z

Add "loongson,ls2k0300-rtc" dedicated compatible to represent the RTC interface of the Loongson-2K0300 chip. Its hardware design is similar to that of the Loongson-1B, but it does not support the alarm feature.

dt-bindings: rtc: loongson: Correct Loongson-1C interrupts property

2026-01-30T23:12:31Z

The `interrupts` property indicates an RTC alarm interrupt, which is required for RTCs that support the alarm feature, which is not supported by the Loongson-1C RTC. We exclude it for a more accurate description. Changing the `allowed` property is ABI-breaking behavior, but throughout the existing Loongson DTS{i}, the description of the RTC nodes conforms to the modified bingding rules. Thus, the existing Loongson DTS{i} will not be affected.
