[PATCH v5 00/10] Designware PWM driver updates

From: Ben Dooks
Date: Wed Oct 05 2022 - 18:12:56 EST


This is an updated version of the Designware PWM driver updates
for OF support, which now splits the driver into PCI and OF parts
as well as tries to sort out the review comments.

I think I have sorted all the review comments out, but this has been
rather difficult to find time to finish due to other work and being
ill.

Series history;

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
