The SA8155p is similar to SM8150 and we can reuse most things, but I
think we can afford to add qcom,sa8155p in the DT bindings.

Naturally sm8150 should be part of this list, but please also add
sa8155p as well.

And please split this in two (one qcom,sm8150-mtp and qcom,sm8150, and
one qcom,sa8155p-adp and qcom,sa8155p).

And note that this is saying that your compatible needs to be one of the
enum entries, followed by the const, but in your dts you only specified
qcom,sa8155p-adp. It needs to be:

	compatible = "qcom,sa8155p-adp", "qcom,sa8155p";

Thanks,
Bjorn
