I have now booted the 4.9-rc1 kernel. Pyra works fine.
GTA04 charging and USB-gadget work :) So it might indeed be no longer needed.

But GTA04 reports spuriously during inactivity:

looks as if someone patched the driver to make this a required property but forgot to update twl4030.dtsi or whatever...

Yes, there are recent patches:

iMac:master hns$ git blame drivers/regulator/core.c | fgrep "ramp_delay not set"
73e705bf81 (Matthias Kaehlcke        2016-09-14 09:52:08 -0700 2763) 		rdev_warn(rdev, "ramp_delay not set\n");
iMac:master hns$
