There is no such property in the bindings.

NAK, there is no such property.

How is this related to

? Looks like duplicate :/

Are they similar? Maybe you should share board DTSI?

No, why? Drop it. There is no user.
Also, do not top post.

No, they are not similar. They just use the same SoC but they are on
different system boards with different electronic schematic.

Thanks for your advice, I will change this property to
"aspeed,int-vref-microvolt" which is defined in the binding in the v2

Hi Krzysztof,
I will change this property to the "aspeed,int-vref-microvolt" which
is defined in the binding that can choose the ADC internal reference
voltage is 1200000 or 2500000 µV, and will add these changes to the v2
patches.
