Subject: [PATCH v10 06/11] drm/sun4i: dsi: Probe tcon0 during dsi_bind
Date: Mon, 20 May 2019 14:33:13 +0530	[thread overview]
Message-ID: <20190520090318.27570-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190520090318.27570-1-jagan@amarulasolutions.com>

Probe tcon0 during dsi_bind, so-that the tcon attributes like
divider value, clock rates are available whenever it required.

Tested-by: Merlijn Wajer <merlijn@wizzup.org>
