ubwc_swizzle ? I'd suppose it's 6, but I'd bet on it.
I don't see ubwc_swizzle defined for any other platform, and it seems to
be unused for DPU_HW_UBWC_VER_40. Am I perhaps missing something?
Yes, it doesn't seem to be used for VER_40, just wanted to have it for
the sake of completeness. See

Please use CTL_SC7270_MASK instead, unless you have a strong reasong not to
do it.
No strong reason, will update.
Thanks. The logic for me is to be able to update a single mask when new
features are added instead of going all over the code.
E.g. I think sc8280xp will benefit from hierarchical DSPP support, will
it not?
Thanks,
Bjorn
