Subject: [PATCH v8 0/2] Imagination Technologies PWM support

A new round for the IMG PWM driver.

The IMG PWM controller is muxed with a PDM controller, through a shared
so-called periph register bit, which sets the output as PWM or PDM.
Because this register is not part of the pin controller block, but rather
PWM/PDM specific, and because the register is also used to set the PDM value,
it is simpler to use a regmap-based syscon to deal with it.

This time, I'm removing the PDM driver from the submission and submitting the PWM
alone. The PDM was written as a misc driver, but had some design issues, so for
now I'm proposing to merge the PWM only.

The series is based on v3.19-rc3. If at all possible I'd like to see this merged
for v3.20.

Comments welcome!
