From 3f3acefb63dc70d767f730045ab7ebaa81938d77 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 11 Apr 2008 22:19:45 +0200 Subject: [PATCH] [ARM] pxa: V4L2 soc_camera driver for PXA270 This patch adds a driver for the Quick Capture Interface on the PXA270. It is based on the original driver from Intel, but has been re-worked multiple times since then, now it also supports the V4L2 API.
