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.
