There are no changes, if not just a simple rebase and another test run on the same hardware. MT6323 is not the only PMIC that has a LEDs controller IP and it was found that the others do have a compatible register layout, except for some register offsets. The logic contained in this driver can be totally reused for other PMICs as well, so I can't see any reason to keep this specific to the MT6323 part. This series brings meaningful platform data to this driver, giving it flexibility and adding support for LED controllers found in the MT6331 and MT6332 PMICs. Tested on MT6795 Sony Xperia M5 smartphone.
