What does it says to you wrt bindings? > Yes, SM6150 uses the same DisplayPort controller IP as SM8150. I wasn’t previously familiar with how fallback compatibility is defined in the bindings. Since SM6150 will be declared as a fallback to sm8350-dp, is it fine to drop the driver patch ([2/2])? Here’s the updated commit message for [1/2], does it match your expectation? 'SM6150 uses the same controller IP as SM8150. Declare SM6150 as a fallback compatible to sm8350-dp for consistency with existing bindings and to ensure correct matching and future clarity.' Thanks again for your guidance.
