Amit Daniel Kachhap 8bf13a4346 clocksource: exynos_mct: Register the timer for stable udelay ... This patch registers the exynos mct clocksource as the current timer as it has constant clock rate. This will generate correct udelay for the exynos platform and avoid using unnecessary calibrated jiffies. This change has been tested on exynos5420 based board and udelay is very close to expected. Without this patch udelay() on exynos5400 / exynos5800 is wildly inaccurate due to big.LITTLE not adjusting loops_per_jiffy correctly. Also without this patch udelay() on exynos5250 can be innacruate during transitions between frequencies < 800 MHz (you'll go 200 MHz -> 800 MHz -> 300 MHz and will run at 800 MHz for a time with the wrong loops_per_jiffy).
