OMAP: DSS2: OMAPFB: Implement auto-update mode
Implement auto-update mode for manual-update displays. omapfb driver uses a delayed work to update the display with a constant rate. The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which previously called omapdss but is now handled inside omapfb, and a new sysfs file, "update_mode". The update interval is by default 20 times per second, but can be changed via "auto_update_freq" module parameter. There is also a new module parameter "auto_update", which will make omapfb start manual update displays in auto-update mode. This auto-update mode can be used for testing if the userspace does not support manual update displays properly. However, it is a very inefficient solution, and should be considered more as a hack for testing than something that could be used as a long term solution.
