dt-bindings: rtc: mxc: Document fsl,imx31-rtc

2025-01-13T08:34:52+00:00

imx31.dtsi uses the following RTC compatible:

compatible = "fsl,imx31-rtc", "fsl,imx21-rtc";

Document 'fsl,imx31-rtc' to fix the following dt-schema warning:

'fsl,imx31-rtc' is not one of ['fsl,imx1-rtc', 'fsl,imx21-rtc']

dt-bindings: mfd: sprd,sc2731: Convert to YAML

2024-11-12T14:48:45+00:00

Convert the Spreadtrum SC27xx PMIC bindings to DT schema. Adjust the
filename to match the compatible of the only in-tree user, SC2731.
Change #interrupt-cells value to 1, as according to [1] that is the
correct value.
Move partial examples of child nodes in the child node schemas to this new
MFD schema to have one complete example.

just add its name and use the R329 as a fallback.

dt-bindings: rtc: mpfs-rtc: remove Lewis from maintainers

2024-11-10T21:12:34+00:00

Lewis hasn't worked at Microchip for a while, and IIRC never actually
worked on the RTC in the first place. Remove him from the maintainers
list in the binding, leaving Daire.

dt-bindings: rtc: renesas,rzg3s-rtc: Document the Renesas RTCA-3 IP

2024-10-31T23:16:16+00:00

Document the RTC IP (RTCA-3) available on the Renesas RZ/G3S SoC.
The RTC IP available on Renesas RZ/V2H is almost identical with the
one found on Renesas RZ/G3S (it misses the time capture functionality
which is not yet implemented on proposed driver). For this, added also a
generic compatible that will be used at the moment as fallback for both
RZ/G3S and RZ/V2H.

dt-bindings: mfd: mediatek: mt6397: Convert to DT schema format

2024-10-16T08:00:38+00:00

Convert the mfd: mediatek: mt6397 binding to DT schema format.

MT6323, MT6358, and MT6397 are PMIC devices with multiple function
subdevices. They share a common PMIC design but have variations in
subdevice combinations.

Key updates in this conversion:

1. RTC:
   - Convert rtc-mt6397.txt and merge into parent MT6397 PMIC DT schema.

2. 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.

Additional updates:
- MAINTAINERS: Add co-maintainers and reference to
  mfd/mediatek,mt6397.yaml for LED and power-controller drivers.
- input/mediatek,pmic-keys.yaml: Update reference to
  mfd/mediatek,mt6397.yaml.
