The X-Powers AXP717 is a PMIC chip, controlled via I2C or RSB. It features four DC/DC converters and a number of linear regulators. Also it contains some charger and USB-C detection circuitry, though we don't use that in U-Boot. The PMIC is used on some newer Allwinner devices, for instance the Anbernic handheld gaming devices.
Add AXP717 support to the DM driven AXP regulator driver, and also an SPL version, as we need to program the DRAM voltage rail correctly before attempting to initialise the DRAM controller.
Cheers, Ander
