Subject: [RESEND PATCH v2 2/2] dt-bindings: pinctrl: pincfg-node: add restrictions on conflicting properties
Date: Tue, 24 Feb 2026 13:39:05 +0000 [thread overview]
Message-ID: <20260224-salami-divisibly-57447839a0f9@wendy> (raw)
In-Reply-To: <20260224-stimulate-fraying-29ac76f6c55e@wendy>
Many of the possible pincfg properties are not compatible with one
another, either because they represent mutually exclusive states for a
pin or because they provide the same information in different units.
Add some simple restrictions to prevent invalid configurations.
