From: Manivannan Sadhasivam <[email protected]> The QMP PHY expects the vdda-phy supply to be around 0.88V and the vdda-pll supply to be 1.2V. But these two supplies are swapped for the USB QMP PHYs on these boards, feeding 1.2V to vdda-phy and 0.9V to vdda-pll. Fix it by swapping the two supplies back.
