dt-bindings: Updates Linus Walleij's mail address

2025-12-16T16:17:59+00:00

My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

dt-bindings: rtc: Add Apple SMC RTC

2025-12-08T21:41:59+00:00

Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC, but most of the PMU functionality is abstracted out by the SMC. An additional RTC offset stored inside NVMEM is required to compute the current date/time.

dt-bindings: rtc: renesas,rz-rtca3: Add RZ/V2H support

2025-12-08T21:28:17+00:00

The Renesas RZ/V2H RTC IP is based on the same RTCA3 IP as RZ/G3S (r9a08g045), with the following differences: - It lacks the time capture functionality - The maximum supported periodic interrupt frequency is 128Hz instead of 256Hz - It requires two reset lines instead of one Add new compatible string "renesas,r9a09g057-rtca3" for RZ/V2H and update the binding accordingly: - Allow "resets" to contain one or two entries depending on the SoC. - Add "reset-names" property, but make it required only for RZ/V2H.

dt-bindings: rtc: Document NVIDIA VRS RTC

2025-11-06T22:50:07+00:00

Add device tree bindings for NVIDIA VRS (Voltage Regulator Specification) RTC device. NVIDIA VRS is a Power Management IC (PMIC) that implements a power sequencing solution with I2C interface. The device includes RTC which provides functionality to get/set system time, retain system time across boot, wake system from suspend and shutdown state. Supported platforms: - NVIDIA Jetson AGX Orin Developer Kit - NVIDIA IGX Orin Development Kit - NVIDIA Jetson Orin NX Developer Kit - NVIDIA Jetson Orin Nano Developer Kit Signed-off-by: Shubhi Garg Reviewed-by: Rob Herring (Arm) Reviewed-by: Jon Hunter Tested-by: Jon Hunter Link: https://patch.msgid.link/20251007135738.487694-2-shgarg@nvidia.com Signed-off-by: Alexandre Belloni
