v1 -> v2: - squash the 2d-array-ification and fixing up the logic into one patch - drop num_variants, loop over VARIANTS_MAX*DSI_MAX unconditionally - drop inadequate Fixes: tags - pick up rbs v1: https://lore.kernel.org/linux-arm-msm/20230211115110.1462920-1-konrad.dybcio@xxxxxxxxxx/ Some DSI host versions are implemented on multiple SoCs which use vastly different register maps. This messes with our current assumptions of being able to map {dsi0, dsi1} to {reg0, reg1}. Solve that by adding a way of specifying multiple sets of base registers and try comparing them against the register specified in DT until we find a match. This removes the need for the QCM2290-specific compatible which was used in the SM6115 DT (which uses DSIv2.4.1, just like SC7180). The series also takes care of that.
