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.
v5:
* Drop a patch applied to the gpio tree
* Fix patch 4/4 description typo (Uwe)
* Reduce the number of multiplications (Uwe)
* Add spaces around '+' (Uwe)
* Use '1ULL' instead of explicit cast to reduce verbosity
* Add Linus' Reviewed-by tags to patches that are unchanged since v2
v4:
* Take advantage of zero value being treated as 2^32 by hardware. Rewrite
patch 5/5 (Uwe).
v3:
* Improve patch 3/5 description (Uwe)
* Add more Reviewed-by tags from Uwe
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
Baruch Siach (4):
gpio: mvebu: improve pwm period calculation accuracy
gpio: mvebu: make pwm .get_state closer to idempotent
gpio: mvebu: don't limit pwm period/duty_cycle to UINT_MAX
gpio: mvebu: improve handling of pwm zero on/off values
