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 .../allwinner,sun20i-d1-analog-ldos.yaml | 65 +++++ .../allwinner,sun20i-d1-system-ldos.yaml | 57 +++++ .../allwinner,sun4i-a10-system-control.yaml | 3 + drivers/regulator/Kconfig | 8 + drivers/regulator/Makefile | 1 + drivers/regulator/sun20i-regulator.c | 232 ++++++++++++++++++ drivers/soc/sunxi/sunxi_sram.c | 3 + 7 files changed, 369 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/allwinner,sun20i-d1-analog-ldos.yaml create mode 100644 Documentation/devicetree/bindings/regulator/allwinner,sun20i-d1-system-ldos.yaml create mode 100644 drivers/regulator/sun20i-regulator.c -- 2.35.1
