It includes DT binding documentation, the ma35d1 rtc driver, and device tree updates. The ma35d1 rtc controller provides real-time and calendar messaging capabilities. It supports programmable time tick and alarm match interrupts. The time and calendar messages are expressed in BCD format. This rtc driver has been tested on the ma35d1 som board with Linux 6.5-rc2. v2: - Updated nuvoton,ma35d1-rtc.yaml - Modified patch title and fixed typo - Added reference to rtc.yaml - Used unevaluatedProperties instead of additionalProperties - Modified rtc driver - Used dev_err_probe() - Removed ma35d1_rtc_remove() - Made other minor fixes Jacky Huang (3): dt-bindings: rtc: Add Nuvoton ma35d1 rtc arm64: dts: nuvoton: Add rtc for ma35d1 rtc: Add driver for Nuvoton ma35d1 rtc controller .../bindings/rtc/nuvoton,ma35d1-rtc.yaml | 48 +++ .../boot/dts/nuvoton/ma35d1-iot-512m.dts | 4 + .../boot/dts/nuvoton/ma35d1-som-256m.dts | 4 + arch/arm64/boot/dts/nuvoton/ma35d1.dtsi | 8 + drivers/rtc/Kconfig | 11 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-ma35d1.c | 355 ++++++++++++++++++ 7 files changed, 431 insertions(+) create mode 100644 Documentation/devicetree/bindings/rtc/nuvoton,ma35d1-rtc.yaml create mode 100644 drivers/rtc/rtc-ma35d1.c
