From 7d1365c998a462d8ea3627e87526227556b63351 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Fri, 18 Nov 2011 15:39:52 +0200 Subject: [PATCH] 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.
