Subject: [PATCH v7 05/23] drm/sun4i: tcon: Export get tcon0 routine
Date: Fri,  1 Feb 2019 21:12:14 +0530
Message-ID: <20190201154232.10505-6-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190201154232.10505-1-jagan@amarulasolutions.com>

Sometimes tcon attributes like tcon divider, clock rate etc are needed
in interface drivers like DSI. So for such cases interface driver must
probe the respective tcon and get the attributes.

Since tcon0 probe is already available, via sun4i_get_tcon0 function,
export the same instead of probing tcon explicitly.
