Now that a header exists with macros for the media interface bus-type
values, replace hardcoding numerical constants with the corresponding
macros in the DT sources.

sorry for this late answer. Is it possible to split ARM DT patches by
vendor ?


Sure. Is that only to ease backporting, or do you want the ST part to be
merged through a different tree ?
I usually take all STM32 DT patches in my stm32-next branch. It's to avoid merge issue at arm-soc maintainer level. 

thanks
alex
