Message

This series adds a few related fixes to the pwm .apply and .get_state 
callbacks.

The first patch was originally part of the series adding Armada 8K/7K pwm 
support. I split it out to a separate series following review comments from 
Uwe Kleine-König who spotted a few more issues. There is no dependency between 
this and the Armada 8K/7K series.

Baruch Siach (5):
  gpio: mvebu: fix pwm get_state period calculation
  gpio: mvebu: improve pwm period calculation accuracy
  gpio: mvebu: make pwm apply/get_state closer to idempotent
  gpio: mvebu: don't limit pwm period/duty_cycle to UINT_MAX
  gpio: mvebu: document zero pwm duty cycle limitation
