this patch has a bunch of issues that were already fixed during discussions
with Martijn as part of his effort to prepare an initial device tree for
PinephonePro. (also noted below for your reference)

I suggest to wait for the original author's submission.

kind regards,

^^ these are general indicator LEDs, they don't have a function marked on the
chasis of the phone.

^^^ this is not a regulator and doesn't switch on VBUS supply
for type-c port. That's done by the otg_switch

^^^ these are not mainline bindings

Mainline uses mode-switch / orientation-switch / usb-role-switch properties and
altmodes node. Specified VDO (0x001c0c00) is also incorrect. And I don't think
the phone can provide 1.4A at 5V (that would be 7W)

VCC5V0_SYS can provide at most 2A and it's shared between modem, power amp for
the speaker, and type-c VCONN which also has some power requirements (1W).

^^^ this does not work. fusb0 doesn't provide any extcon interface
it only consumes one, just like tcphy0
