2023-11-23dt-bindings: backlight: mp3309c: Remove two required propertiesFlavio Suligoi1-6/+4
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>

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.

2023-08-18dt-bindings: leds: Document pull-up supply for interrupt and I2CStephan Gerhold1-0/+6
Since the interrupt and I2C lines of AW2013 operate in open drain low active mode a pull-up supply is needed for correct operation. Unfortunately there is no ideal place to describe it in the DT: The pull-up needed for the I2C lines could be described on the I2C bus. However, the pull-up needed for the interrupt line belongs neither directly to the interrupt controller nor to AW2013. Since the AW2013 driver will be typically in control of the power management and interrupt masking it makes more sense to describe it inside the AW2013 device tree node. Add it to the AW2013 DT schema together with a comment that makes it clear what exactly it represents.

AW2013 has an optional interrupt pin "INTN" which is used to report completion of started operations (e.g. power up or LED breath effects).

Normally, the maximum brightness is determined by the hardware, and this property is not required. This property is used to set a software limit. It could happen that an LED is made so bright that it gets damaged or causes damage due to restrictions in a specific system, such as mounting conditions. Note that this flag is mainly used for PWM-LEDs, where it is not possible to map brightness to current. Drivers for other controllers should use led-max-microamp.
