   4 Subject: ARM: dts: imx25: Fix PWM "per" clocks
   5
   6 From: Fabio Estevam <fabio.estevam@freescale.com>
   7
   8 commit 7ecd0bde5bfea524a843ad8fa8cb66ccbce68779 upstream.
   9
  10 Currently PWM functionality is broken on mx25 due to the wrong assignment of the
  11 PWM "per" clock.
  12
  13 According to Documentation/devicetree/bindings/clock/imx25-clock.txt:
  14         pwm_ipg_per             52
  15
  16 ,so update the pwm "per" to use 'pwm_ipg_per' instead of 'per10' clock.
  17
  18 With this change PWM can work fine on mx25.
