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"
