Hi Bryan,

Thanks for making the changes. I only have some minor nitpicks now:

s4_p1/p2 are specified twice, is this on purpose or accidental?

On purpose I believe.

@Dmitry ?

Please add

hnp-disable;
srp-disable;
adp-disable;

here for consistency with msm8916.dtsi. These are needed for correct
behavior if you enable CONFIG_USB_OTG_FSM, see commit bfd5d21abcd5c

Hmm, I haven't noticed any problems with OTG - then again, I'm looking at my kernel config and +# CONFIG_USB_OTG_FSM is not set
