From 20676a4c9503dbcbb283c4c6565426dc63b81775 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Wed, 21 Mar 2012 06:21:30 -0300 Subject: [PATCH] [media] s5p-fimc: Don't use platform data for CSI data alignment configuration The MIPI-CSI2 data alignment parameter can be derived from media bus pixel code, so it can be now dropped from the platform data structure. This is a prerequisite for adding the device tree support. Once this patch is merged the corresponding fields will be removed from the drivers' public headers and corresponding board files.
