[PATCH 3/7] pwm: pwm-tiehrpwm: Update the clock handling of pwm-tiehrpwm driver

From: Philip Avinash
Date: Wed Jan 02 2013 - 08:25:16 EST

The clock framework has changed and it's now better to invoke
clock_prepare_enable() and clk_disable_unprepare() rather than the
legacy clk_enable() and clk_disable() calls. This patch converts the
pwm-tiehrpwm driver to the new framework.

In 3.8-rc1, common clock frame work support added to AM335x.
