Subject: [PATCH v3 0/4] regulator: Add support for Allwinner D1 LDOs
Date:   Sun, 14 Aug 2022 23:34:31 -0500

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

A binding and driver change is required for the SRAM controller, to
accept the regulators device as its child node. The new example in the
SRAM controller binding uses the compatible string added in this series:
https://lore.kernel.org/lkml/20220815041248.53268-1-samuel@sholland.org/

Changes in v3:
 - Add "reg" property to bindings
 - Add "unevaluatedProperties: true" to regulator nodes
 - Minor changes to regulator node name patterns
 - Remove system-ldos example (now added in patch 3)
 - Adjust control flow in sun20i_regulator_get_regmap() for clarity
 - Require the regulators node to have a unit address
 - Reference the regulator schema from the SRAM controller schema
 - Move the system LDOs example to the SRAM controller schema
 - Reorder the patches so the example passes validation

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
