Subject: [PATCH 23/27] drm: sun4i: add quirks for TCON TOP
Date: Sun, 2 Sep 2018 09:26:39 +0200 [thread overview]
Message-ID: <20180902072643.4917-24-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20180902072643.4917-1-jernej.skrabec@siol.net>
From: Icenowy Zheng <icenowy@aosc.io>
Some SoCs, such as H6, doesn't have a full-featured TCON TOP.
Add quirks support for TCON TOP.
Currently the presence of TCON_TV1 and DSI is controlled via the quirks
structure.
