From: Stephan Gerhold <stephan.gerhold@xxxxxxxxxx>
commit 26a1b22aaf0c6f5128f8d0242caf3d983d5a2836 upstream.
On the X1E80100 CRD, &vreg_l3e_1p2 only powers &usb_mp_qmpphy0/1
(i.e. USBSS_3 and USBSS_4). The QMP PHYs for USB_0, USB_1 and USB_2
are actually powered by &vreg_l2j_1p2.
Since x1e80100-dell-xps13-9345 mostly just mirrors the power supplies from
the x1e80100-crd device tree, assume that the fix also applies here.
