Subject: [PATCH v2 1/3] dt-bindings: pinctrl: starfive,jh7110: add PAD_INTERNAL_* virtual pins
Date: Thu, 24 Apr 2025 14:20:15 +0800 [thread overview]
Message-ID: <20250424062017.652969-2-uwu@icenowy.me> (raw)
In-Reply-To: <20250424062017.652969-1-uwu@icenowy.me>
The JH7110 SoC could support internal GPI signals to be routed to not
external GPIO but internal low/high levels.
Add two macros, PAD_INTERNAL_LOW and PAD_INTERNAL_HIGH, as two virtual
"pads" to represent internal GPI sources with fixed low/high levels.
