Just to clarify, do you mean split the patch into two?

For brask, we are not adding GFX devices at the moment. Its DDI and TCP usages are quite different from chromebooks: not all TCP are used for DP on USB-C, and DDIA is sometimes used for DP on USB-C. We are still exploring how GFX devices should be added for chromebox.
