2025-06-01dt-bindings: rtc: rzn1: add optional second clockWolfram Sang
The external crystal can be a second clock input. It is needed for the SCMP counting method which allows using crystals different than 32768Hz. It is also needed for an upcoming SoC which only supports the SCMP method.

RTC tracks clock time during system suspend and it is used as a wakeup source on S32G2/S32G3 architecture. RTC from S32G2/S32G3 is not battery-powered and it is not kept alive during system reset.

2025-05-24dt-bindings: rtc: qcom-pm8xxx: add uefi-variable offsetJohan Hovold
On many Qualcomm platforms the PMIC RTC control and time registers are read-only so that the RTC time can not be updated. Instead an offset needs be stored in some machine-specific non-volatile memory, which a driver can take into account. On platforms where the offset is stored in a Qualcomm specific UEFI variable the variables are also accessed in a non-standard way, which means that the OS cannot assume that the variable service is available by the time the RTC driver probes. Add a 'qcom,uefi-rtc-info' boolean flag to indicate that the RTC offset is stored in a Qualcomm specific UEFI variable so that the OS can determine whether to wait for it to become available. The UEFI variable is 882f8c2b-9646-435f-8de5-f208ff80c1bd-RTCInfo and holds a 12-byte structure where the first four bytes is a GPS time offset in little-endian byte order.

Regulators: - Align to generic name "regulators". - Update references from .txt to .yaml for mt6323, mt6358, and mt6397 regulators. - Simplify regulator name labels in device tree examples. 3. Audio Codec: - Simplify Audio Codec part with updating compatible items. - Align to generic name "audio-codec" for codec and sound subdevices. 4. Clocks: - Align to generic name "clocks" for clockbuffer subdevices. 5. LEDs: - Convert leds-mt6323.txt and merge into parent MT6397 PMIC DT schema. - Update LED binding. 6. Keys: - Add detailed descriptions for power and home keys. - Add compatible: mediatek,mt6358-keys. 7. Power Controller: - Convert mt6323-poweroff.txt and merge into parent MT6397 PMIC DT schema. - Add #power-domain-cells property to fix dt-binding check error. - Clarify "BBPU" as "Baseband power up". 8. Pinctrl: - Align to generic name "pinctrl" instead of "pin-controller". 9. Compatible: - Drop "mediatek,mt6357" since there is a separated DT Schema for PMIC MT6357. 10. Examples: - MT6323: Retain complete examples for this PMIC. - MT6358 and MT6397: simplify settings in regulators. - Preserve "audio-codec", "clocks", "pinctrl", "rtc", and "keys" sections as they contain typical settings for different PMICs.
