3.13.11-ckt16 -stable review patch. If anyone has any objections, please let
me know.
------------------
From: Fabio Estevam <fabio.este...@freescale.com>
commit 7ecd0bde5bfea524a843ad8fa8cb66ccbce68779 upstream.
Currently PWM functionality is broken on mx25 due to the wrong assignment of the
PWM "per" clock.
According to Documentation/devicetree/bindings/clock/imx25-clock.txt:
pwm_ipg_per 52
,so update the pwm "per" to use 'pwm_ipg_per' instead of 'per10' clock.
With this change PWM can work fine on mx25.
