Right, there is an open question [2] in PATCH v2 08/12 if this patch
should have been part of Emil's ccache series or I will send it in v3
of my series.

There shouldn't be any additional Kconfig changes or dependencies as
those patches just extend an already existing driver. There were some
changes in v2, but they are still compatible with this series (I've
retested that to make sure).
My tree is based on next-20231024, so I'm going to rebase it onto
next-20231117, to exclude the possibility of a regression somewhere.
I will also test with renesas-drivers.
Thanks,
Cristian
