Subject: [PATCH V3 4/7] ARM: OMAP2+: Simplify system timers definitions
Date: Mon, 4 Feb 2013 13:46:33 -0600	[thread overview]
Message-ID: <1360007196-21350-5-git-send-email-jon-hunter@ti.com> (raw)
In-Reply-To: <1360007196-21350-1-git-send-email-jon-hunter@ti.com>

There is a lot of redundancy in the definitions for the various system
timers for OMAP2+ devices. For example, the omap3_am33xx_gptimer_timer_init()
function is the same as the omap3_gp_gptimer_timer_init() function and the
function omap4_sync32k_timer_init() can be re-used for OMAP5 devices.
Therefore, consolidate the definitions to simplify the code.
