---
Changes for v3:
- Use sun50i-a64-amarula-relic.dts name
- add eldo3 for dvdd-csi
- update dldo4 min voltage as 3.3v as per schematics
- use dldo3 name as dovdd-csi
- update aldo1, aldo2 voltages as per schematics Changes for v2:
- Rename dts name to sun50i-a64-relic.dts which is simple to use

You claim that this is doing OTG...

While you have an ID pin and a controllable VBUS. Which one is it?

Though it claims OTG, board doesn't have any USB ports to operate(not even Mini-AB) the only way to use the board as peripheral to transfer images from host.

I'm not sure what you mean here. If there's no USB connector, why do you even enable it?

I'm saying there is no host port on board. Board has connector header[1] comes with few pins includes USB D+, D-, ID, VBUS, GROUND, UART0 TX, RX etc. we have to connect wires to these pins to make pluggable USB to host pc. and here USB pins used for transferring data from host pc to target board like in peripheral mode.
Hope you understand.

I'm still unsure how it's relevant. If the wire is plugged on your board's header, is there anything that prevents using it as a host assuming you have a proper connector on the other end of your wire?
