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. Signed-off-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Tony Lindgren <tony@atomide.com>
