From: Vikram Sethi <vikrams@codeaurora.org>

This patch introduces a Qualcomm Technologies, Inc HiDMA
device and allows the instantiation of the vfio-qcom-hidma
device from the QEMU command line
(-device vfio-qcom-hidma,host="<device>").

A device tree node is created for the guest containing compat,
dma-coherent, reg and interrupts properties.

If I am not wrong you miss the dc->vmsd = &vfio_platform_vmstate
(VMStateDescription attachement)

This will cause an error with CLANG - I got that one already, reported
by Peter ;-) -

error: unused variable
'vfio_platform_vmstate' [-Werror,-Wunused-const-variable]

Yes, the current HiDMA driver that we are attempting to upstream uses
