Hi,

I'd like to know how we can proceed with these patches. It would be
great if someone could have a look at them. If this a bandwidth
problem please say so and I'll stay calm for another round ;)

This is the third round of patches for adding perf support to the
rockchip-dfi driver. The binding changes seem to be sorted out now,
would be great to get some feedback to the driver changes as well.
