2025-09-16dt-bindings: leds: Unify 'leds' propertyAleksandrs Vinarskis
A number of existing schemas use 'leds' property to provide phandle-array of LED(s) to the consumer. Additionally, with the upcoming privacy-led support in device-tree, v4l2 subnode could be a LED consumer, meaning that all camera sensors should support 'leds' and 'led-names' property via common 'video-interface-devices.yaml'. To avoid duplication, unify 'leds' property from existing schemas to newly introduced 'led-consumer.yaml'.

git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds Pull LED updates from Lee Jones: "Improvements & Fixes: - A fix for QCOM Flash to prevent incorrect register access when the driver is re-bound. This is solved by duplicating a static register array during the probe function, which prevents register addresses from being miscalculated after multiple binds - The LP50xx driver now correctly handles the 'reg' property in device tree child nodes to ensure the multi_index is set correctly. This prevents issues where LEDs could be controlled incorrectly if the device tree nodes were processed in a different order. An error is returned if the reg property is missing or out of range - Add a Kconfig dependency on between TPS6131x and V4L2_FLASH_LED_CLASS to prevent a build failure when the driver is built-in and the V4L2 flash infrastructure is a loadable module - Fix a potential buffer overflow warning in PCA955x reported by older GCC versions by using a more precise format specifier when creating the default LED label. Cleanups & Refactoring: - Correct the MAINTAINERS file entry for the TPS6131X flash LED driver to point to the correct device tree binding file name - Fix a comment in the Flash Class for the flash_timeout setter to "flash timeout" from "flash duration" for accuracy - The of_led_get() function is no longer exported as it has no users outside of its own module. Removals: - Revert the commit to configure LED blink intervals for hardware offload in the Netdev Trigger. This change was found to break existing PHY drivers by putting their LEDs into a permanent, unconditional blinking state. Device Tree Bindings Updates: - Update the binding for LP50xx to document that the child reg property is the index within the LED bank.

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.
