Add a field to the host_set called 'flags' (was host_set_flags changed to suit Jeff) Add a simplex_claimed field so we can remember who owns the DMA channel Add a ->mode_filter() hook to allow drivers to filter modes Add docs for mode_filter and set_mode Filter according to simplex state Filter cable in core This provides the needed framework to support all the mode rules found in the PATA world. The simplex filter deals with 'to spec' simplex DMA systems found in older chips. The cable filter avoids duplicating the same rules in each chip driver with PATA. Finally the mode filter is neccessary because drive/chip combinations have errata that forbid certain modes with some drives or types of ATA object. Drive speed setup remains per channel for now and the filters now use the framework Tejun put into place which cleans them up a lot from the older libata-pata patches.
