Subject: [PATCH v7 06/23] drm/sun4i: sun6i_mipi_dsi: Probe tcon0 during dsi_bind
Date: Fri, 1 Feb 2019 21:12:15 +0530 [thread overview]
Message-ID: <20190201154232.10505-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190201154232.10505-1-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>
