From 28f59339f72d191e24e0f97f156a481dd5c3db65 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 13 Mar 2009 06:08:20 -0300 Subject: V4L/DVB (11030): soc-camera: add board hook to specify the buswidth for camera sensors Camera sensors have a native bus width say support, but on some boards not all sensor data lines are connected to the image interface and thus support a different bus width than the sensors native one. Some boards even have a bus driver which dynamically switches between different bus widths with a GPIO. This patch adds a hook which board code can use to support different bus widths.
