commit 636b45b8efa91db05553840b6c0120d6fa6b94fa upstream.
The current set minimum voltage of 730000µV seems to be wrong. I don't know the document which specifies that but the imx6qdl datasheets says that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed, lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).
