This series adds support for the power controller found in D1 and other recent Allwinner SoCs. There is no first-party documentation, but there are a couple of vendor drivers for different hardware revisions[1][2], and the register definitions were easy to verify empirically. I have tested this driver on D1 with the video engine. There is no DT update patch here to avoid dependencies between series. The example in the binding is what will go in the D1 DT.
