[PATCH 00/10] Add additional i2c buses

[Alex Deucher]

At the momemt we only expose the i2c buses used by the driver
for displays or EEPROMs.  However, some OEMs/AIBs use extra i2c
buses for things like RGB controls. Expose the extra i2c buses in
case the OEM uses one of them.

Alex Deucher (10):
  drm/amd/display/dm: drop extra parameters to create_i2c()
  drm/amd/display/dm: drop hw_support check in amdgpu_dm_i2c_xfer()
  drm/amd/display/dc: add a new helper to fetch the OEM ddc_service
  drm/amd/display/dm: handle OEM i2c buses in i2c functions
  drm/amd/display/dm: add support for OEM i2c bus
  drm/amd/display/dc: add support for oem i2c in atom_firmware_info_v3_1
  drm/amd/display/dc: enable oem i2c support for DCE 12.x
  drm/amdgpu/atombios: drop empty function
  drm/amdgpu: rework i2c init and fini
  drm/amdgpu: add OEM i2c bus for polaris chips
