From 5a3a388fbefac3705dfcde16c93fc81e6fd9378f Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Mon, 12 Nov 2007 23:24:02 -0800 Subject: ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer code On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by setting the source to be the 32k clock instead of sys_clk. This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp code. Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based clocksource is not used. Instead the default 32k sync counter is used as the clocksource (see the clocksource in plat-omap/common.c.) This is important for sleep/suspend so there is a valid counter during sleep. Note that the suspend/sleep code needs fixing to check for overflows of this counter. In addition, the OMAP2/3 details are removed from timer32k.c leaving that with only OMAP1 specifics. A follow-up patch will move it from plat-omap common code to mach-omap1.
