Hi Rob,

I have another patch series which enables the type C node and adds QMP
PHY driver changes for setting the SS lane select MUX.

https://patchwork.kernel.org/project/linux-arm-msm/list/?series=361971

Just wanted to work on getting a PMIC based type C driver out there,
which can be utilized in designs where the QMP PHY lane select mux is
not going to be used. (ie using a FUSB340 as a lane select mux instead
of the QMP PHY mux)

Thanks

Regards,
Wesley Cheng
