Hi,

@Patrice
Would you agree to make the device-tree patches go through drm-misc 
instead of your tree ? So that the breaking change lands in -next in the 
same time as the driver changes.

I will send another series to convert display subsystem bindings to DT 
schema as soon as the series is merged.

@Alain
Do you prefer to merge it yourself or you rather let me do it ?

Best regards,
