From 1a96edd70c1f4b4a1904803f8a83900087f4d1da Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 1 Oct 2010 16:37:00 -0700 Subject: [PATCH] OMAP1: Add support for SoC camera interface This patch adds a definition of the OMAP1 camera interface platform device, and a function that allows for providing a board specific platform data. The device will be used with the upcoming OMAP1 SoC camera interface driver.
