Subject: [PATCH v3 9/9] arm64: dts: rockchip: fix touchscreen reset GPIO polarity
Date: Mon,  5 Dec 2022 14:40:38 +0100	[thread overview]
Message-ID: <20221103-upstream-goodix-reset-v3-9-0975809eb183@theobroma-systems.com> (raw)
In-Reply-To: <20221103-upstream-goodix-reset-v3-0-0975809eb183@theobroma-systems.com>

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

The reset line is active low for the Goodix touchscreen controller so
let's fix the polarity in the Device Tree node.
