OK that looks good to me thanks. Good to hear you got it sorted out.
The 8250_dw style runtime PM is a good solution for simple cases. Where
it won't work are SoCs where runtime PM calls need to propagate up the
bus hierarchy. For example, 8250_omap needs runtime PM calls for the
interconnect and power domain to get register access working.

OK seems like we're good to go then :)
