Armada 370/XP devices can 'blink' gpio lines with a configurable on
and off period. This can be modelled as a PWM.
However, there are only two sets of PWM configuration registers for
all the gpio lines. This driver simply allows a single gpio line per
gpio chip of 32 lines to be used as a PWM. Att
Now that the gpio driver also supports PWM operation, enable
the PWM framework in mvebu_v7_defconfig.

This patchset starts out with some cleanups and fixes for the mvebu
gpio driver. Then new functionality is added. The Armada 370 and XP
SoC has the ability to "blink" the gpio lines at a configuration on
and off duration. So simple PWM support is added. However only a
single gpio line per gpio chip

Use the new gpiod_get_array and gpiod_put_array functions for obtaining and
disposing of GPIO descriptors.

This doesn't disable and unprepare the clock.

Hi,
It will be easy to forget adding this when adding new subdirectories.
Can we do this instead?

Patch applied, and conjured a patch doing the same on the other
subdirs
When drivers are compiled in subdirectories the -DDEBUG flag need
to be passed in the individual Makefiles.

Lennert/Arnaud: is any one of you guys still maintaining and testing
IOP stuff so you can say something about this patch?
Or should I just apply it?

Richard can you look at this patch and even test it maybe?
Do you still work with the Timberdale hardware or do you
know anyone who does?

of_get_named_gpiod_flags fails with -EPROBE_DEFER in cases
where the gpio chip is available and the GPIO translation fails.
This causes drivers to be re-probed erroneusly, and hides the
real problem(i.e. the GPIO number being out of range).
