This series adds bindings and a driver for the two pairs of LDOs
inside the Allwinner D1 SoC.

A preparatory binding and driver change is required for the SRAM
controller, so the regulators device can be its child node.

Changes in v2:
 - Remove syscon property from bindings
 - Update binding examples to fix warnings and provide context
 - Use decimal numbers for .n_voltages instead of field widths
 - Get the regmap from the parent device instead of a property/phandle

Samuel Holland (4):
  dt-bindings: sram: sunxi-sram: Add optional regulators child
  soc: sunxi: sram: Only iterate over SRAM children
  regulator: dt-bindings: Add Allwinner D1 LDOs
  regulator: sun20i: Add support for Allwinner D1 LDOs
