Subject: [PATCH 2/3] dt-bindings: ads7846: Add hsync-gpios
Date: Tue, 30 Apr 2024 09:03:48 +0200 [thread overview]
Message-ID: <20240430-gpio-leds-miscarm-v1-2-9c94d7711f6c@linaro.org> (raw)
In-Reply-To: <20240430-gpio-leds-miscarm-v1-0-9c94d7711f6c@linaro.org>
The TI ADS7846 emits a horizontal sync signal that is usually
connected to a GPIO for polling. Add a binding for this.
