I already did. The first problem is you are breaking compatibility here
(a kernel with these changes won't work with a dtb without these
changes). As I previously said, this binding in general is horribly
designed and full on Linux driver specifics. The first clue is your
driver changes are resulting in DT changes. If you are going to break
compatibility here, it better be redoing this binding. The problems I
see with this binding are:
- Linux device name strings
- "charger-manager" is not a chip or circuit. DT describes the h/w.
- Current limits by type of USB connection are pointless. These are part
of the spec.
- Properties need standard unit suffixes.
- A mixture of battery and charger properties.
