Luca, this patch looks good as-is (without diving into the values).

Dmitry, I see some things that we may improve here..

1. Rename msm8xab to msm89ab or something, it's really inconsistent
   with other drivers

2. Some values seem very common / always constant.. perhaps we could
   add some #defines like we do in DPU?

3. Can we add some magic defines to make flush_hw_mask non-cryptic?

4. We can probably use pointers in data structs and deduplicate identical
   blocks!

I really would not like to go the DPU way here. Maybe we can define the 
'full-featured' masks, while leaving the older hardware intact.

Sounds like a good idea, especially since we have all the defines. I'll 
tend to it after landing 8226.

Let's see.
