Subject: [PATCH v3 09/13] drm/bridge: tc358762: Fix sync polarities
Date: Wed, 13 May 2026 16:10:18 +0300 [thread overview]
Message-ID: <20260513-tc358762-fixes-v3-9-6698b55008b9@ideasonboard.com> (raw)
In-Reply-To: <20260513-tc358762-fixes-v3-0-6698b55008b9@ideasonboard.com>
Setting LCDCTRL_HSYNC_POL and LCDCTRL_VSYNC_POL will make the respective
sync signal active high. The driver does this in inverse. Fix it.
