[PATCH v4 00/17] pwm: Add support for PWM Capture

This patch-set makes use of the new Capture API by supplying PWM
Capture functionality into the already existing STi PWM driver.

v3 => v4:
- Keep DTB backward compatibilty

v2 => v3:
- Supply DT documentation changes
- Submit DTS additions as part of this set
- Default Capture and PWM-out number of channels to 0
  - Do additional checking, to ensure at least one channel is requested
  - Use global locking, instead of lock in device data

v1 => v2:
- API change
- Use a struct to carry the result back to the caller
- Use 'struct pwm' to store device specific data
- Make timeout configurable
- Don't use clear_bit(), instead use raw bit logic
- Propagate return value of platform_get_irq()
- Don't cast to (void *)
- Move to subsystem terminology (channels => devices)
- Remove channel select feature
- Enable Capture IP during capture
