That's not needed. We will use the fallback compatible which is 
"mediatek,mt6765-spi" which will take the correct DT data. If in the future we 
realize that mt8192 has a difference in the HW we can add the compatible. 
Otherwise with the binding description we should be fine

So you mean that only the following binding patch is needed?
