From 3675c750cf2effc6a2d9582cd1b9d3043aded3b6 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 6 Jan 2010 18:42:16 +0900 Subject: soc-camera: ov772x: Modify buswidth control This patch removes "buswidth" struct member, and sets the default buswidth to the natively supported 10 bit. You can select 8 bit buswidth by new flag.
