From 6722a4016d7f5f107a82ad71a3ee1ccec105532f Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 17 Nov 2010 06:44:54 +0000 Subject: [PATCH] fbdev: sh_mipi_dsi: Allow LCDC board callbacks Update the MIPI-DSI driver to make use of the LCD panel callbacks in the LCDC platform data. Without this patch MIPI panels cannot use board specific LCDC callbacks to control power and/or back light.
