Subject: [PATCH v5 3/4] dt-bindings: sram: sunxi-sram: Add regulators child
Date: Thu, 8 Dec 2022 02:41:26 -0600 [thread overview]
Message-ID: <20221208084127.17443-4-samuel@sholland.org> (raw)
In-Reply-To: <20221208084127.17443-1-samuel@sholland.org>
Some sunxi SoCs have in-package regulators controlled by a register in
the system control MMIO block. Allow a child node for this regulator
device in addition to SRAM child nodes.
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

(no changes since v4)
Changes in v4:
- Remove unevaluatedProperties from regulators schema reference
Changes in v3:
- 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:
- New patch for v2
