This patch series adds support for Kinetic KTD3137 backlight IC. It supports linear brightness range from 0 to 2047.
While the chip supports PWM and MSB modes, they weren't included, since MSB mode supports only 8-bit brightness range, and PWM is not enabled on this board. I have checked other Xiaomi vendor kernels, and their configuration appear to be the same as on my board. I'm not aware if any device uses PWM mode with this chip. This series was developed and tested on the Xiaomi Redmi Note 9 board.
