This patch adds support HRT for machines of S5P64X0 and S5PV210. Basically, PWM Timer3 is used for clockevent and PWM Timer4 is used for clocksource. Since PWM Timer3 is used for other purpose, PWM Timer2 is used on SMDKV210. Signed-off-by: Sangbeom Kim <sbkim73@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
