Subject: [media] omap3isp: Add set performance callback in isp platform data Author: Laurent Pinchart <[email protected]> Date: Thu Mar 3 10:05:22 2011 -0300 Replace the omap_pm_set_min_bus_tput() with a callback to board code. This makes the omap3isp driver compilable as a module, and lets board code manage OMAP PM details depending on board requirements.
