Subject: [PATCH v5 1/4] regulator: dt-bindings: Add Allwinner D1 system LDOs
Date:   Thu,  8 Dec 2022 02:41:24 -0600

The Allwinner D1 SoC contains two pairs of in-package LDOs. The pair of
"system" LDOs is for general purpose use. LDOA generally powers the
board's 1.8 V rail. LDOB powers the in-package DRAM, where applicable.

(no changes since v4)

Changes in v4:
 - Fix the order of the maintainer/description sections
 - Replace unevaluatedProperties with "additionalProperties: false"
 - Drop the analog LDOs until the codec binding is ready

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 the parent binding)

Changes in v2:
 - Remove syscon property from bindings
 - Update binding examples to fix warnings and provide context
