Hi Maxime,

Now that Dmitry has queued up the firmware-name property changes in his for-linus branch, these dt patches are ready for merging.

I queued this for 4.10.

Thanks!
Maxime

Yes, the arm-soc maintainers usually stop merging PR after -rc6. It's still a bit flexible is something major and not really huge comes up, but for that kind of patches, I usually start queuing patches for the next release when -rc6 is out.
