From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tomi Valkeinen Date: Tue, 22 Nov 2011 09:21:46 +0000 Subject: [PATCH 47/65] OMAPDSS: DISPC: add dispc_mgr_get_framedone_irq Message-Id: <1321953724-6350-48-git-send-email-tomi.valkeinen@ti.com> List-Id: References: <1321953724-6350-1-git-send-email-tomi.valkeinen@ti.com> In-Reply-To: <1321953724-6350-1-git-send-email-tomi.valkeinen@ti.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fbdev@vger.kernel.org, linux-omap@vger.kernel.org Cc: archit@ti.com, Tomi Valkeinen 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.
