Subject: [RFC v4 00/10] RFC on synpsys pwm driver changes

New version of the pwm timers patch, hopefully all review comments
are sorted out, however I have not had time to fully test this and
I do not have a PCI system to test it on either.

The series has been moved around a bit to try to get some of the
simpler changes in before splitting and to make the OF driver a
single addition.

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


Ben Dooks (10):
  dt-bindings: pwm: Document Synopsys DesignWare
    snps,pwm-dw-apb-timers-pwm2
  pwm: dwc: allow driver to be built with COMPILE_TEST
  pwm: dwc: change &pci->dev to dev in probe
  pwm: dwc: move memory alloc to own function
  pwm: dwc: use devm_pwmchip_add
  pwm: dwc: split pci out of core driver
  pwm: dwc: make timer clock configurable
  pwm: dwc: add of/platform support
  pwm: dwc: add snps,pwm-number to limit pwm count
  pwm: dwc: add PWM bit unset in get_state call
