[PATCH v2 0/5] gpio: mvebu: pwm fixes and improvements

[Baruch Siach]

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.

v2:

Address Uwe Kleine-König comments.

  * Improve patch 1/5 summary line

  * Add more information to patch 1/5 description

  * Add more information to patch 2/5 description

  * Don't round period/duty_cycle up in .apply (patch 3/5)

  * Expand the comment in path 5/5 based on RMK's analysis of hardware 
    behaviour

  * Add Uwe's Reviewed-by tags
