The bit 4 is 'reserved', so this probably should not cause any issues, but it's better to fix it. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> ss/dsi.c

The current PLL code handles this wrong: instead of waiting for the bit to be cleared, it waits for the bit to be set. Usually, the bit is always set, as the CPU has just set it before. However, if the CPU takes enough time between setting the GO bit and checking it, the HW may already have cleared the bit and this leads to timeout error. Fix the wait to check the bit properly.

Not doing so causes a crash if omapfb is unbound and bound, or omapfb module is removed and loaded, while keeping omapdss around. Fix this by calling unset_manager() for all overlays.

When omapfb is shutting down, it will disable all the overlays. However, instead of actually disabling all the overlays, it disables only all the overlays that are currently attached to framebuffers. On OMAP4+, this leaves the fourth overlay left enabled. Fix the loop so that we actually go through all the overlays. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> mapfb/omapfb-main.c
