From e4008e2240605a64d595f3b9e070bfaf5a6950ff Mon Sep 17 00:00:00 2001 From: Afzal Mohammed Date: Mon, 5 Aug 2013 17:02:32 -0500 Subject: [PATCH] video: da8xx-fb: enable sync lost intr for v2 ip The interrupt handler explicitly has code that handles the sync lost interrupt. However the sync lost interrupt is never actually being enabled in the LCD controller, therefore this interrupt code path is not being exercised. This fix simply enables the generation of the sync lost interrupt by the LCD controller so it can be dealt with appropriately by the interrupt handler.
