Merge tag 'backlight-next-6.20' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/backlight

Pull backlight updates from Lee Jones:
"New Support & Features:

- Add a new driver for the Congatec Board Controller (CGBC)
backlight, providing brightness control via the board controller's
PWM interface

Improvements & Fixes:

- Resolve build failures in the Awinic AW99706 driver by switching to
the correct GPIO consumer header

- Extend the Qualcomm WLED driver to support the specific
over-voltage protection (OVP) values required for the PMI8994 and
PMI8950 variants

Device Tree Bindings Updates:

- Document the device-specific over-voltage protection (OVP)
millivolt ranges and default values for Qualcomm PMI8994 and
PMI8950 WLED controllers"

backlight: Add Congatec Board Controller (CGBC) backlight support

This driver provides backlight brightness control through the Linux
backlight subsystem. It communicates with the board controller to
adjust LCD backlight using PWM signals. Communication is done
through Congatec Board Controller core driver.
