'mhdptx' is redundant. Don't continue that pattern. Just 'dsc'.
so sequence should be mhdptx, j721e-intg, mhdptx-sapb, dsc?

Have you tested this works? While it might work for TI with the
j721e-intg registers in the middle, it won't work for platforms without
them. You're going to have to have 2 lists of reg-names.

I will add two lists one with and one without j721e-integ in the 'if'
condtional
