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
