From 6e740f9a85339c295af8deb5376511fcb2a268ad Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 29 Oct 2012 15:20:45 -0700 Subject: [PATCH] ARM: OMAP: Move omap-pm-noop.c local to mach-omap2 This code should be private to mach-omap2. The only use for it in for omap1 has been in dmtimer.c to check for context loss. However, omap1 does not lose context during idle, so the code is not needed. Further, omap1 timer has OMAP_TIMER_ALWON set, so omap1 was not hitting omap_pm_get_dev_context_loss_count() test.
