Hi Konrad,
Sorry, my explain isn't enough before.

My tested against linux-next + this patchset, all my test code from 
upstream linux-next, haven't downstream code related.

About the temporal patch which enable CONFIG_HVC_DCC, because we haven't 
enable uart, so I enable CONFIG_HVC_DCC for verify if we can get DCC 
console through "make ARCH=arm64 menuconfig" on linux-next/master, but 
this patchset haven't contain this enable CONFIG_HVC_DCC patch, because 
upstream seems don't want to enable CONFIG_HVC_DCC defaultly.

Besides these, I all do dtbs_check and checkpatch.pl check, all these 
check passed.

CONFIG_HVC_DCC is at upstream. It is not necessary to have UART to test 
the kernel w/ the console.

One can boot the kernel w/ JTAG console too. This will allow us to 
submit the patches without submitting the UART / clocks dependencies.
