2024-10-16dt-bindings: mfd: mediatek: mt6397: Convert to DT schema formatMacpaul Lin
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.

2024-10-15dt-bindings: leds: Add 'active-high' propertyDaniel Golle
Other than described in commit c94d1783136e ("dt-bindings: net: phy: Make LED active-low property common") the absence of the 'active-low' property means not to touch the polarity settings which are inherited from reset defaults, the bootloader or bootstrap configuration. Hence, in order to override a LED pin being active-high in case of the default, bootloader or bootstrap setting being active-low an additional property 'active-high' is required. Document that property and make it mutually exclusive to the existing 'active-low' property.

2023-11-23dt-bindings: backlight: mp3309c: Remove two required propertiesFlavio Suligoi
The two properties: - max-brightness - default brightness are not really required, so they can be removed from the "required" section. The "max-brightness" is no longer used in the current version of the driver (it was used only in the first version). The "default-brightness", if omitted in the DT, is managed by the device driver, using a default value. This value depends on the dimming mode used: - for the "analog mode", via I2C commands, this value is fixed by hardware (=31) - while in case of pwm mode the default used is the last value of the brightness-levels array. Also the brightness-levels array is not required: - in "analog mode", via I2C commands, the brightness-level array is fixed by hardware (0..31).; - in pwm dimming mode, the driver uses a default array of 0..255 and the "default-brightness" is the last one, which is "255" NOTE: there are no compatibility problems with the previous version, since the device driver has not yet been included in any kernel. Only this dt-binding yaml file is already included in the current v6.7.0-rc1 kernel version. No developer may have used it. Other changes: - improve the backlight working mode description, in the "description" section - update the example, removing the "max-brightness" and introducing the "brightess-levels" property Signed-off-by: Flavio Suligoi <f.suligoi@asem.it> Acked-by: Conor Dooley <conor.dooley@microchip.com> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Link: https://lore.kernel.org/r/20231116105319.957600-2-f.suligoi@asem.it Signed-off-by: Lee Jones <lee@kernel.org>
