  An updated set of patches for the Designware PWM driver
split into PCI and OF versions. I think I got all the
review issues in this set.

Sorry for the delay in getting this out, between conferences
and other absences there has been little time to deal with
this set. I will be now out of office until 3rd Jan 2023.

v7:
 - fixup kconfig from previous pcie changes
 - re-order kconfig to make dwc core be selected by PCI driver
 - move clk variable to patch it is used in
v6:
 - fix removal ordering of DWC_PERIOD_NS
v5:
 - fixed kconfig string error
 - merged pwm-nr into main of code
 - split of code from pci code
 - updated pwm-nr capping
 - fix duplicate error reporting in of-code
 - fix return in of-probe
 - remove unecessary remove function as devm_ functions sort this
 - fixed ordering of properties
 - added missing reg item
 - fixed missing split of the two clock sources.
 - get bus clock in of code
v4:
 - split pci and of into new modules
 - fixup review comments
 - fix typos in dt-bindings
v3:
- change the compatible name
- squash down pwm count patch
- fixup patch naming
v2:
- fix #pwm-cells count to be 3
- fix indetation 
- merge the two clock patches
- add HAS_IOMEM as a config dependency

Hi, how's the progress on review and getting this set finalised?

Speaking for me:

Your patch set isn't forgotton. It's just that my time is limited and
reviewing a new driver is time intensive.

I'm sorry I cannot give feedback in a more timely manner, but I will
come to it eventually.

Best regards
Uwe

I had some comments for patches #6 and #10. Patches #7 - #9 are still
marked as new in the PWM patchwork, but I will mark them as
changes-requested in the assumption that you'll have to rework them to
address my feedback for the other two patches anyhow.

Best regards
Uwe
