Merge tag 'leds-for-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
- Add a new LED common module for ti-lmu driver family
- Modify MFD ti-lmu bindings
- add ti,brightness-resolution
- add the ramp up/down property
- Add regulator support for LM36274 driver to lm363x-regulator.c
- New LED class drivers with DT bindings:
- leds-spi-byte
- leds-lm36274
- leds-lm3697 (move the support from MFD to LED subsystem)
- Simplify getting the I2C adapter of a client:
- leds-tca6507
- leds-pca955x
- Convert LED documentation to ReST
