Subject: [PATCH v6 06/22] drm/sun4i: sun6i_mipi_dsi: Probe tcon0 during dsi_bind
Date: Fri, 25 Jan 2019 01:28:44 +0530 [thread overview]
Message-ID: <20190124195900.22620-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190124195900.22620-1-jagan@amarulasolutions.com>
Probe tcon0 during dsi_bind, so-that the tcon attributes like
divider value, clock rate can get whenever it need.
