Subject: [PATCH v2 1/4] dt-bindings: reset: nuvoton,ma35d1-reset: add simple-mfd and child node support
Date: Thu, 25 Jun 2026 10:39:55 +0800 [thread overview]
Message-ID: <20260625023958.569299-2-a0987203069@gmail.com> (raw)
In-Reply-To: <20260625023958.569299-1-a0987203069@gmail.com>
The MA35D1 system-management syscon node hosts the USB PHY register
block at offset 0x60. To model usb-phy@60 as a DT child of the syscon
node the binding must allow:
- simple-mfd as an optional third compatible so the MFD core can
instantiate child platform devices.
- #address-cells and #size-cells (each const: 1) so child nodes can
carry a reg property.
- An open child-node pattern (patternProperties "^.*@[0-9a-f]+$")
to pass dt-schema validation.
