This patch series adds support for the MediaTek MT8196 SoC in the CMDQ
driver and related subsystems. The changes include adding compatible
names and properties, updating driver data to accommodate hardware
changes, and modifying the CMDQ API to support non-subsys ID hardware.

Hello Jason,
I had a fast look at the changes that you're proposing with this series.
The reasons behind this are more or less understood on my side, but the
actual changes look a bit odd in the sense that passing a physical address
like this, on a first glance, not only looks like it may be dangerous, but
also looks like there's a lot of room for improvement.
Can you please point me at some driver/code (or a reference downsream kernel
for this SoC, which would be even better) so that I can take a look at how
is that being used?
Thanks,
Angelo
