[U-Boot] Nvidia Trega Tk1 - /cpus/cpu@0 missing clock-frequency property

[U-Boot] Nvidia Trega Tk1 - /cpus/cpu@0 missing clock-frequency property

Hi,

 Currently I am working on an Nvidia Jetson Tk1 board.

With u-boot v2016.05 I am seeing the following messages on the start up

I am not sure about what's the issue here. Google search shows
something might be missing in the device tree. Can you let me know
whats the issue here.

Mit Freundlichen Gr??en

The DTB file that's passed to the kernel should be the DTB file built 
along with the kernel binary. If you're already doing that, and there 
are still problems, I suggest discussing this on the Tegra kernel 
mailing list; those messages are all kernel messages and nothing to do 
with U-Boot.

(BTW, the -517 messages aren't actually errors; they're expected 
behaviour when a device attempts to initialize and the dependencies it 
needs are not yet available. The initialization will be retried later 
and should succeed then).
