As per shematics VDDIO_AO18, VDDIO_AO3V3/VDD3V3 DDR3_1V5/DDR_VDDC:
fixed regulator output which is supplied by P5V0.

Rename vcc3v3 regulator node to vddio_ao3v3 as per shematics.

typo: "schematics"

according to the schematics there's both:
- VDDIO_AO3V3
- VCC3V3 (which is turned on by VDDIO_AO3V3, see [0])

personally I would call this (along with the node name and alias) DDR3_1V5
odroid-c2_rev0.1_20150930.pdf shows that DDR3_1V5 and DDR_VDDC are
both the same. however, the DDR_VDDC signal name is not used by any
component in the datasheet

odroid-c2_rev0.1_20150930.pdf uses VCC3V3 as supply

Hi Martin,

Thanks for your review comments.

Their have been some revision changes in S905 Odroid Schematics.
[0] https://dn.odroid.com/S905/Schematic/

Well I have make my changes based on old odroid-c2_rev0.2_20151218.pdf

OK. next time will run spell check before I send these changes.

From the schematics it seams same.

VDDIO_AO3V3---DMG340LSQN4 (Q4)---VCC3V3

But this name change was done to link TFLASH_VDD_EN to TFLASH_VDD for eMMC

VDDIO_AO3V3-----TFLASH_VDD using  TFLASH_VDD_EN gpio pin.

Well I have tested this changes on eMMC module.

Ok Thanks I will change this to DDR3_1V5 as per the datasheet.

yes, they are the same signal. the only difference is that VCC3V3 is
turned on later in the power-up sequence

I cannot see any of the TFLASH_* regulators being linked to eMMC (they
are only linked to the SD card slot, I also checked
odroid-c2_rev0.2_20151218.pdf and odroid-c2_rev0.2_20171114.pdf).
which page of the odroid-c2_rev0.2_20151218.pdf schematics shows how
TFLASH_VDD is linked to eMMC?

please note that I don't have an Odroid-C2 board myself (so I cannot
test any of this).

Thanks I will double check again and re-post then with correction again.
