SpacemiT K1 is an ideal chip for some new extension such as RISC-V Vector
1.0 and Zicond evaluation now. Add initial support for it to allow more
people to participate in building drivers to mainline for it.
This kernel has been tested upon Banana Pi BPI-F3 board on vendor U-Boot
bootflow generated by Armbian SDK[1] and patched OpenSBI[2] to enable
Zicboz, which does not in the vendor dts on its U-Boot. Then successfully
booted to busybox on initrd with this log[3].
As previous discussion in patch v1[4], maintainer expect more basic drivers
ready before really merging it, which would be fine. For other follow-up patches,
that are clk, pinctrl/gpio, reset.. My current goal would target at a headless
system including SD card, emmc, and ethernet.
P.S: talked to Yangyu, I will help and take care of this patch series, thanks

Changes in v2:
- fix timebase-frequency according to current setting
- add other uart dt nodes, fix input frequency
- introduce new uart compatible for K1 SoC
- add 'k1' prefix to bananapi-f3.dts
- fix k1-clint compatible
- fix some typos

Could you look at v1 again and add those to whatever other comments I leave when I take a closer look? Thanks, Conor.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.
