pwm: Replace axi-pwmgen driver by a backport of the mainline driver
Browse files Browse the repository at this point in the history 
Backporting involved several changes. These were marked using some cpp
magic to simplify updates to newer kernel version and for documentation
purposes.

The relevant semantical changes are:

 - The apply callback uses round down now to match the policy upstream.

 - The compatible string changed. All devicetrees are updated
   accordingly.

 - The v1 hardware revision isn't supported any more.
   The v1 documentation isn't in the public documentations any more, so
   this is expected to be ok.
