From 52c6979628d596018e9259767bff4def25e449dc Mon Sep 17 00:00:00 2001

Subject: [PATCH 022/117] dt-bindings: sram: sunxi-sram: Add optional
regulators child
Some sunxi SoCs have in-package regulators controlled by a register in
the system control MMIO block. Allow a child node for these regulators
in addition to SRAM child nodes.
Commit-changes: 2
- New patch for v2
Series-changes: 3
- 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
Series-changes: 4
- Remove unevaluatedProperties from regulators schema reference
