Subject: [PATCH 25/27] drm: sun4i: add support for H6 TCON TOP
Date:   Sun,  2 Sep 2018 09:26:41 +0200
Message-Id: <20180902072643.4917-26-jernej.skrabec@siol.net>
In-Reply-To: <20180902072643.4917-1-jernej.skrabec@siol.net>
References: <20180902072643.4917-1-jernej.skrabec@siol.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Icenowy Zheng <icenowy@aosc.io>

The TCON TOP on Allwinner H6 SoC is a cut down version of the R40 TCON
TOP, which dropped TCON_TV1 and DSI (which do not exist on H6).

Add support for it.
