Add Device Tree bindings for Texas Instruments LM3509 - a High Efficiency Boost for White LED's and/or OLED Displays Signed-off-by: Patrick Gansterer Reviewed-by: Krzysztof Kozlowski Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20240526105136.721529-2-paroga@paroga.com Signed-off-by: Lee Jones

dt-bindings: backlight: qcom-wled: Fix bouncing email addresses

2024-03-07T09:03:28Z

Bjorn is no longer at Linaro. Update his email address to @kernel to match the .mailmap entry. The servers for @codeaurora are long retired and messages sent there will bounce. Update Kiran's email address to match the .mailmap entry. This will help anyone that is looking to reach out about this binding and is not using .mailmap to pre-process their message.

dt-bindings: backlight: Add Kinetic KTD2801 binding

2024-03-07T08:45:11Z

KTD2801 is a LED backlight driver IC found in samsung,coreprimevelte. The brightness can be set using PWM or the ExpressWire protocol. Add a DT binding for the KTD2801.

dt-bindings: backlight: mp3309c: Remove two required properties

2023-11-23T14:54:18Z

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 Acked-by: Conor Dooley Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20231116105319.957600-2-f.suligoi@asem.it Signed-off-by: Lee Jones

dt-bindings: mfd: max8925: Convert to DT schema format

2023-11-01T10:02:17Z

Convert the binding to DT schema format. The sub-functions of this MFD device do not have their own compatible string and are thus described directly in the MFD binding document after being converted to YAML.

dt-bindings: backlight: Add MPS MP3309C

2023-09-28T14:03:06Z

The Monolithic Power (MPS) MP3309C is a WLED step-up converter, featuring a programmable switching frequency to optimize efficiency. The brightness can be controlled either by I2C commands (called "analog" mode) or by a PWM input signal (PWM mode). This driver supports both modes.
