From a6c90657443144be8ea43b5491205d4d72bd03a6 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 13 Mar 2009 10:08:20 +0100 Subject: soc-camera: add board hook to specify the buswidth for camera sensors From: Sascha Hauer 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.
