Subject: [PATCH v2 0/2] Support for Texas Instruments TPS6131X flash LED
 driver

The TPS61310/TPS61311 is a flash LED driver with I2C interface. Its power
stage is capable of supplying a maximum total current of roughly 1500mA.
The TPS6131x provides three constant-current sinks, capable of sinking up
to 2 × 400mA (LED1 and LED3) and 800mA (LED2) in flash mode. In torch mode
each sink (LED1, LED2, LED3) supports currents up to 175m

Changes in v2:
- Bindings: Extend device description
- Bindings: Drop unused address/size cells
- Bindings: Use fallback compatible 
- Bindings: Corrected minimum current for 50mA steps
- Bindings: Drop node label
- Fix name of REGISTER4 INDC shift define
- Save device instead i2c_client in private data
- Add comment for mutex
- Use macro to convert from uA to mA
- Use defines to describe initial register values
- Add safety delay during reset sequence
- Use fixed value enum to set the mode
- Renamed some local variables
- Re-sorted local variables
- Replaced ifdefs for V4L2_FLASH_LED_CLASS
- Improved some error messages
- Link to v1: https://lore.kernel.org/r/20250228-leds-tps6131x-v1-0-d1071d90f9ea@emfend.at
