Refer to the Note of Table 6. Operating Ranges in IMX6DQAEC(Rev.4).
6 VDD_SOC_CAP and VDD_PU_CAP must be equal.
7 VDD_SOC LDO output set point is equal to the VDD_PU LDO output set point.
But, VDD_PU LDO is off in uboot or DVFS processing with VDD_SOC LDO enabled in jb4.2.2_1.1.0.
Does this have the possibility to cause a problem?
(Some issue wasn't seen on custom board.)
