I guess the best > option would be to explicitly add eth parameter to the register macros, what do you think? I don't think there's a best known practice, you'll have to exercise your judgment. Taking a look at a random example of MTK_PDMA_INT_STATUS. Looks like that one is already assigned to eth->tx_int_status_reg. Maybe that can be generalized? Personally I'd forgo the macros completely and just use eth->soc->register_name in the code.
