The undefined registers are treated as 0, which is the DONE2\nregister on the affected platforms. This could cause the DONE2 register\nto have an incorrect value, which could cause Linux to re-initialize the\nPMIC unnecessarily.\n\nTo avoid this issue and ensure that we only write to registers that are\ndefined on a given platform, we can add some more capability flags to\nconditionally call any register writes that aren't common to all\nplatforms.\n\nThere are also a couple of other cleanups that we do along the way.
