Subject: [PATCH 08/19] fbdev: sh_mipi_dsi: Use the LCDC entity default mode
Date: Thu, 16 Aug 2012 13:00:43 +0000 [thread overview]
Message-ID: <1345122054-16013-9-git-send-email-laurent.pinchart@ideasonboard.com> (raw)
Configure the MIPI-DSI transmitter using the LCDC entity default mode
instead of accessing the mode through the LCDC platform data.
