Subject: [PATCH v4 09/13] drm/bridge: tc358762: Fix sync polarities
Date: Mon, 07 Sep 2026 14:28:04 +0300 [thread overview]
Message-ID: <20260907-tc358762-fixes-v4-9-e3fc3ab5cd83@ideasonboard.com> (raw)
In-Reply-To: <20260907-tc358762-fixes-v4-0-e3fc3ab5cd83@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.
