-Device Tree Bindings for LED support on MT6323 PMIC
-
-MT6323 LED controller is subfunction provided by MT6323 PMIC, so the LED
-controllers are defined as the subnode of the function node provided by MT6323
-PMIC controller that is being defined as one kind of Muti-Function Device (MFD)
-using shared bus called PMIC wrapper for each subfunction to access remote
-MT6323 PMIC hardware.
-
-For MT6323 MFD bindings see:
-Documentation/devicetree/bindings/mfd/mt6397.txt
-For MediaTek PMIC wrapper bindings see:
-Documentation/devicetree/bindings/soc/mediatek/mediatek,pwrap.yaml
-
-Required properties:
-- compatible : Must be one of
- - "mediatek,mt6323-led"
- - "mediatek,mt6331-led"
- - "mediatek,mt6332-led"
-- address-cells : Must be 1
-- size-cells : Must be 0
-
-Each led is represented as a child node of the mediatek,mt6323-led that
-describes the initial behavior for each LED physically and currently only four
-LED child nodes can be supported.
-
-Required properties for the LED child node:
-- reg : LED channel number (0..3)
-
-Optional properties for the LED child node:
-- label : See Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger : See Documentation/devicetree/bindings/leds/common.txt

+description: |
+ MT6397/MT6323 is a power management system chip.
+ Please see the sub-modules below for supported features.
+
+ MT6397/MT6323 is a multifunction device with the following sub modules:
+ - Regulators
+ - RTC
+ - Audio codec
+ - GPIO
+ - Clock
+ - LED
+ - Keys
+ - Power controller
+
+ It is interfaced to host controller using SPI interface by a proprietary hardware
+ called PMIC wrapper or pwrap. MT6397/MT6323 PMIC is a child device of pwrap.
+ See the following for pwrap node definitions:

MEDIATEK RANDOM NUMBER GENERATOR SUPPORT
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: - Convert sound/mt6358.txt and merge into parent MT6397 PMIC DT schema. - Align to generic name "audio-codec" for codec and sound subdevices. - Add "mediatek,dmic-mode" and "Avdd-supply" properties. 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. 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.

[2] https://lore.kernel.org/all/20240826-slurp-earphone-0d5173923ae8@spud/ - Keep the $ref for regulators since dt_binding_check didn't report any issue based on linux-next/master repo. - Fix description of mt6397/mt6323 devices, use "power management chip" instead of "multifunction device" - Drop unnecessary comments or description according to the review. - Convert sub-modules to DT Schema: - RTC, LEDs, power-controllers, regulators - Drop duplicate sub node name and description for sub-modules - RTC, Keys - examples: - drop parent pwrap node - Add examples from mediatek,mt6323-regulator.yaml - Add examples from mediatek,mt6358-regulator.yaml - Add examples from mediatek,mt6397-regulator.yaml - Complete the examples as could as possible. Changes for v3: - Rebased on linux-next/master git repo near next-20240906. - Revise commit message. - Regulators: - Use "additionalProperties: true" and add "contains" for matching $ref DT bindings. - Simplify regulator name labels in device tree examples. - LEDs: - Use LED bindings. - Squash following patches in v2 for removing old text format DT bindings into this patch, includes: - leds-mt6323.txt, mt6323-poweroff.txt, rtc-mt6397.txt, sound/mt6358.txt. - Fix file format of DT schemas, add blank between properties. - Fix 'make checkrefdoc' errors, update reference in mediatek,pmic-keys.yaml. Changes for v4: - Remove "mediatek,mt6357" from PMIC's compatible string since there is a seperated DT schema for PMIC mt6357.
