OMAPDSS: DISPC: add dispc_mgr_get_framedone_irq
Add dispc_mgr_get_framedone_irq() which returns the irq number for FRAMEDONE for the given channel. Note that the function returns always 0 for DIGIT channel, even if OMAP4 does have FRAMEDONE_TV interrupt. The reason for this is that this function is currently used only to track manual updates, and thus FRAMEDONE_TV is not needed. If there's need in the future to also get the FRAMEDONE_TV this needs revisiting. However, as FRAMEDONE_TV doesn't exist on OMAP2/3, the use of this function for that purpose needs some extra code to handle the OMAP2/3 case. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
