-Subject: [PATCH] firmware: arm_scmi: Add per message transport data
-
-The virtio transport in this patch series can be simplified by using the
-scmi_xfer tx/rx buffers for data exchange with the virtio device, and
-for saving the message state. But the virtio transport requires
-prepending a transport-specific header. Also, for data exchange using
-virtqueues, the tx and rx buffers should not overlap.
-
-The first step to solve the aforementioned issues is to add a
-transport-specific data pointer to scmi_xfer.
