From 8d978a88e6ccfa809879667de4098068be8efb5c Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 8 Dec 2014 13:16:03 -0800 Subject: rk3288/exynos5250/exynos5420: Consolidate timer files Some boards spread their timer implementation out in multiple files with one function each for no discernable reason. Let's clean that up to make things a little simpler to find. BRANCH=None BUG=None TEST=Booted Pinky, compiled Daisy and Pit.
