No, not all pseudo-devices have a pseudo-device-parent node:
1. Not even all pseudo-devices appear in the device tree; only
ones which need to have children do.
2. The parent of pseudo-devices that are in the device tree is
ROOT. It would be fine with me to change it to PSEUDO (and
define such a value, obviously), but then you'd need to make
sure that all the places that test for ROOT also test for
PSEUDO.

That is actually orthogonal to how the pseudo-device is attached.
