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.
