From 2d3f595016f982294c1669ee87aa91179d88502b Mon Sep 17 00:00:00 2001 From: Sekhar Nori Date: Mon, 16 Nov 2009 17:21:30 +0530 Subject: davinci: cp_intc: provide set_wake function There is nothing special to be done for interrupts which can wakeup the device from sleep on CP-INTC, but not having a set_wake implemented prevents use of common drivers which expect this function to be implemented for all wakeup interrupt sources. This patch fixes the issue encountered when using the omap-rtc driver on DA850. On DA850 the RTC alarm interrupt is used to wake up the SoC from deep sleep mode. Without this patch, the disable_irq_wake throws an unbalanced wake disable warning while resuming because the previous enable call fails for lack of set_wake implementation.
