Subject: [PATCH 2/6] ARM: OMAP: omap camera builds again; Mistral init and mux
From: David Brownell <dbrownell@...rs.sourceforge.net>
Support the camera connector on the OSK Mistral add-on board:
- define muxing for both camera controllers
- mux both of them for Mistral
- teach ov9640 glue about mistral powerup/powerdown
