Subject: [PATCH v3 2/9] drm/sun4i: tcon: Add TCON LCD support for R40
Date: Tue, 31 Dec 2019 18:35:21 +0530 [thread overview]
Message-ID: <20191231130528.20669-3-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191231130528.20669-1-jagan@amarulasolutions.com>
TCON LCD0, LCD1 in allwinner R40, are used for managing
LCD interfaces like RGB, LVDS and DSI.
Like TCON TV0, TV1 these LCD0, LCD1 are also managed via
tcon top.
Add support for it, in tcon driver.
