There are no legitimate uses of this field in the kernel, only a few stale references and two drivers that abuse the field as a side-channel between the dmaengine driver and its client. Let's change the xilinx and qualcomm drivers to use the documented side-channel (peripheral_data) instead, and remove the remnants of it to prevent new users from coming in. As the last patch in the series depends on all the others, it would be nice have everything merged into the dmaengine tree for v5.17.
