The timeouts are based on different DSI clocks, so the possible range for the timeouts vary greatly depending on the clocks. Also, the multipliers used with the timeouts cause big gaps in the timeout range, meaning that the nanosecond based functions could cause the timeout to be quite far from the intended value. This patch changes the functions to take the plain tick values with the multiplier enable/disable bits, and sets the TA/LP_RX/HS_TX timeouts to maximum. While the timeouts could be much lower, the fact is that when TA/LP_RX/HS_TX timeout happens, we are in an error situation and not in a hurry anyway. STOP_STATE_COUNTER is a different matter, but it is only used at initialization time, and won't normally affect the performance. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

What happens is something like this: - User presses a key context 1: - drivers/char/keyboard.c calls schedule_console_callback() - fb_unblank takes the console semaphore - dsi bus lock is taken, and frame transfer is started (dsi bus lock is left on) - Unblank code tries to set the panel backlight, which tries to take dsi bus lock, but is blocked while the frame transfer is going on context 2, shared workqueue, console_callback in drivers/char/vt.c: - Tries to take console semaphore - Blocks, as console semaphore is being held by context 1 - No other shared workqueue work can be run context 3, HW irq, caused by FRAMEDONE interrupt: - Interrupt handler schedules framedone-work in shared workqueue - Framedone-work is never ran, as the shared workqueue is blocked. This means that the unblank thread stays blocked, which means that context 2 stays blocked. While I think the real problem is in keyboard/virtual terminal code, using a private workqueue in the DSI driver is perhaps safer and more robust than using the shared one. The DSI works should not be delayed more than a millisecond or so, and even if the private workqueue gives us no hard promise of doing so, it's still safer bet than the shared workqueue.

It's now possible to select the memory region used by the framebuffer device using the new mem_idx parameter of omapfb_plane_info. If the mem_idx is specified it will be interpreted as an index into the memory regions array, if it's not specified the framebuffer's index is used instead. So by default each framebuffer keeps using it's own memory region which preserves backwards compatibility. This allows cloning the same memory region to several overlays and yet each overlay can be controlled independently since they can be associated with separate framebuffer devices.

If eg. VID1 starts out completely outside the update area but VID2 causes the update area to increase in such a way that VID1 now falls partially within the increased update area VID1 should be rechecked and the update area possibly increased even further to fully encompass VID1. So simply keep looping over the overlays until such time that none of the overlays caused the update area to change.

To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.

As a result, DIU continues to display using old area descriptor even if the new one has been written to the descriptor register of the plane. Add the code from Freescale MPC5121EADS BSP for writing descriptor addresses properly. This fixes the problem for Rev 2.0 silicon.
