From 0b30ec1cb7f1b0134b16670f886baaf3521b083c Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Tue, 5 Jun 2012 12:34:56 -0500 Subject: [PATCH] ARM: OMAP: Remove timer function pointer for context loss counter For OMAP2+ devices, a function pointer that returns the number of times a timer power domain has lost context is passed to the dmtimer driver. This function pointer is only populated for OMAP2+ devices and it is pointing to a platform function. Given that this is a platform function, we can simplify the code by removing the function pointer and referencing the function directly. We can use the OMAP_TIMER_ALWON flag to determine if we need to call this function for OMAP1 and OMAP2+ devices. The benefit of this change is the we can remove the function pointer from the platform data and simplifies the dmtimer migration to device-tree.
