[PATCH v3] ARM: dts: add bcm2835-pwm bindings

[Bart Tanghe]

To probe the bcm2835-pwm driver properly, this dts bindings has to be added 
to the bcm2835 dtsi file.
In expectation of a bcm2835 clock driver, I've added fixed-clock clock binding.

Changes in v3:
 - node added by reg value

The pwm node still seems to be in the wrong place. Sorting by reg value, 
it should be after i2c@20205000 and before sdhci@7e300000, as I 
mentioned before.

I'm really sorry. I've used the wrong source. I make v4.

Regards,
