I'm wondering if it's possible to add support for KCAL interface. It is a third party kernel patch that adjusts RGB multiplier, and provides /sys interfaces.
There are many popular devices which got KCAL port (it even made into some official CM branches). With this interface, one can adjust color temperature even the Qualcomm driver does not work.
Any thoughts on this?
I know there's going to be some effort mapping the colors but.. this is Android, and there are different drivers/ interfaces anyway, and KCAL is a relatively straightforward one so I guess it's worth looking into IMHO.
