Merge tag 'cache-for-v6.19' of https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers-late
standalone cache drivers for v6.19
ccache:
Add a compatible for the pic64gx SoC. No driver change needed, as it
falls back to the PolarFire SoC.
hisi hha/generic cpu cache maintenance:
Add support for a non-architectural mechanism for invalidating memory
regions, needed for some cxl implementations on arm64 (and probably
elsewhere in the future). The HiSilicon Hydra Home Agent is the first
driver to provide this support.
