From 7bdc83f74f9636fb40a472e1e02fcaf2cc643115 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 11 Jan 2013 19:17:38 -0600 Subject: [PATCH] ARM: OMAP2+: Simplify system timer clock definitions In commit c59b537 (ARM: OMAP2+: Simplify dmtimer clock aliases), new clock aliases for dmtimers were added to simplify the code. These clock aliases can also be used when configuring the system timers and allow us to remove the current definitions, simplifying the code. Please note that for OMAP4/5 devices (unlike OMAP2/3 devices), there is no clock alias for "timer_sys_ck" with NULL as the device name. Therefore we still need to use the alias "sys_clkin_ck" for these devices.
