V4:
  Fix dt_bindings check
  The same patchset was wrongly posted as V2, 
  https://patchwork.kernel.org/cover/11485107/

This is a splited part from V2:
ARM: imx7ulp: add cpufreq using cpufreq-dt
https://patchwork.kernel.org/cover/11390589/
Nothing changed

The original V2 patchset is to support i.MX7ULP cpufreq,
still waiting the virtual clk being accepted. so to decouple,
this patchset only takes the run mode part.

Peng Fan (4):
  dt-bindings: fsl: add i.MX7ULP PMC binding doc
  ARM: dts: imx7ulp: add pmc node
  ARM: imx: imx7ulp: support HSRUN mode
  ARM: imx: cpuidle-imx7ulp: Stop mode disallowed when HSRUN

Hi Rob,

Could I have your A-b for this patch?

Thanks,
