While one could simply extend the bitfield for older hardware, that would allow data from reserved bits into the driver code, which is generally a bad idea on principle. So this patch instead passes in the client ID mask from from the per-SoC MC data. There's no MC support for T210 (yet), but when that support winds up in the kernel, the appropriate soc->client_id_mask value for that chip will be 0xff. Based on an original patch by David Ung .
