So model it accordingly and use reg-mux to describe the hbmc_mux. Signed-off-by: Nishanth Menon Signed-off-by: Vaishnav Achath --- V2->V3: * Keep register regions unchanged as it is correct according to memory map. * Update commit messages as per Vignesh's suggestion. V1->V2: * Address feedback from Udit to limit the FSS register region size as per TRM. * Use reg-mux changes to simplify the hbmc-mux modelling. * Update commit message to reflect changes.
