This series basically adds support for a QCA8334 ethernet switch to the
qca8k driver. It is a four-port variant of the already supported seven
port QCA8337. Register map is the same for the whole familly and all chips
have the same device ID.

Major part of this series enhances the CPU port setting. Currently the CPU
port is not set to any sensible defaults compatible with the xGMII
interface. This series forces the CPU port to its maximum bandwidth and
also allows to adjust the new defaults using fixed-link device tree
sub-node.

Alongside these changes I fixed two checkpatch warnings regarding SPDX and
redundant parentheses.

Looks great, thanks Michal! Do you have any features or things you are
working on that would be added later to the driver?

Thank you too Florian. And also big thank to you Andrew. You helped me
a lot to debug the RGMII issue. I have been stuck at that for more than
a month and would not resolve it without your help.

As I have done this in a process of upgrading our BSP to a more recent
kernel, and hopefully mainline, I now need to move on to other parts of
the board. So unfortunately no, I do not have any other enhancements
planned to this driver for now. But as we are probably one of the few
with access to the NDA covered Qualcomm documentation I see a great
opportunity to work on that later. I am afraid "later" means something
like next year in this case as I am basically the only kernel developer
in our company and not yet very experienced.

Thank you all for your time,
Michal
