Subject: [PATCH 3/7] pwm: pwm-tiehrpwm: Update the clock handling of pwm-tiehrpwm driver
Date: Wed, 2 Jan 2013 18:54:50 +0530 [thread overview]
Message-ID: <1357133094-30806-4-git-send-email-avinashphilip@ti.com> (raw)
In-Reply-To: <1357133094-30806-1-git-send-email-avinashphilip@ti.com>
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.
