2023-07-14soc: sunxi: Move power-domain driver to the genpd dirUlf Hansson
To simplify with maintenance let's move the sunxi power-domain driver to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS.

2023-01-27soc: sunxi: Add Allwinner D1 PPU driverSamuel Holland
The PPU contains a series of identical MMIO register ranges, one for each power domain. Each range contains control/status bits for a clock gate, reset line, output gates, and a power switch. (The clock and reset are separate from, and in addition to, the bits in the CCU.) It also contains a hardware power sequence engine to control the other bits.
