It would be worth commenting that where bit settings are unknown, they
are taken from the default values in the available public data. I
refer to (for example) the addition of MAT_CONTRL_MAT_SC(1) to the
REG_MAT_CONTRL register in this patch.
The other register ordering changes should also be documented.
However, in my brief test, I haven't noticed any visible detrimental
effects.
