This is not related at all to this patchset.

Neither is this.

This goes to different patchset. Don't mix with SoC changes or pure
bindings. Your CC list is too big.

Different patchset.

As well, with bindings.

Please organize your patchset according to standard SoC upstream
guidelines - don't mix SoC with non-Soc upstreaming or other subsystems.
While putting entire SoC in one patchset is tempting, you added here
totally unrelated changes like PMIC drivers. Result: 33 patches and huge
cc-list bouncing from mailing lists.
