i.MX RT1170 VDD_SOC_IN vs. VDDA_SOC_IN

Can someone confirm whether VDD_SOC_IN and VDDA_SOC_IN are referencing the same voltage domain? IMXRT1170CEC Rev2 only mentions VDD_SOC_IN. IMXRT1170RM Rev1 mentions both VDD_SOC_IN and VDDA_SOC_IN, but doesn't mention whether they are related, at least not as far as I can tell.

Edits:

I also noticed that VDDA_MIPI_1P8 is only found in the RM and VDD_MIPI_1P8 is only found in the datasheet (IMXRT1170CEC).  Are these also the same?  Similar story with VDDA_USB_1P8.  These are more obvious to me to be the same, but I am still trying to understand how the core voltage is boosted with FBB and want to make sure VDD_SOC_IN and VDDA_SOC_IN are the same.

Thanks,
Charlie

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
In my opinion, they all stand for the same pins.
VDD_SOC_IN, VDD_MIPI_1P8 and VDD_USB_1P8 are correct, I'll report the typos for the Doc team for checking.
Have a great day,
TIC
