[PATCH 1/2] pwm: add DT bindings for the STMPE PWM

[PATCH 1/2] pwm: add DT bindings for the STMPE PWM

[Linus Walleij]

This adds fairly standard device tree bindings for the STMPE
PWM found in STMPE24xx multi-purpose expanders.

Shouldn't the node name simply be "pwm"? stmpe_pwm is kind of redundant
given that this is to be embedded in an MFD node that will, presumably,
be called stmpe.
