Subject: [PATCH v8 07/10] drm/sun4i: sun6i_mipi_dsi: Probe tcon0 during dsi_bind
Date: Fri, 15 Feb 2019 01:02:34 +0530 [thread overview]
Message-ID: <20190214193236.7504-8-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190214193236.7504-1-jagan@amarulasolutions.com>
Probe tcon0 during dsi_bind, so-that the tcon attributes like
divider value, clock rate can get whenever it need.
Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
