u-boot VDD_SOC_CAP, VDD_PU_CAP

In the i.mx6 6Dual/6Quad Automotive and Infotainment Applications Processors datasheet rev 2.3 (page 21) it states that -

 

 

 

"VDD_SOC_CAP and VDD_PU_CAP must be equal."

 

However the latest version of i.mx6 u-boot has these voltages set to 1.2 volts and 1.15 volts.

 

I have also read that you can turn off the VDDPU_CAP ldo if VPU and GPU are not used.

 

Is the datasheet correct ?

 

Thanks Doug.
