From: Archit Taneja Date: Fri, 10 Aug 2012 09:31:33 +0000 (+0530) Subject: OMAPDSS: DSI: Maintain copy of pixel format in driver data X-Git-Tag: v3.7-rc1~48^2~1^2~20^2~10 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=02c3960b1eeafd5ed30323e1bb86bfa099b46921;p=~emulex%2Finfiniband.git OMAPDSS: DSI: Maintain copy of pixel format in driver data The DSI driver currently relies on the omap_dss_device struct to receive the desired pixel format of the panel. This makes the DSI interface driver dependent on the omap_dss_device struct. Make the DSI driver data maintain it's own pixel format field. The panel driver is expected to call omapdss_dsi_set_pixel_format() to configure the pixel format before the interface is enabled.
