One of our SoC integrates a hardware block from a hardware vendor. The

willing to provide details of the registers. So I am wondering if I
could use the firmware API (request_firmware) to copy the blob to the
kernel space so that driver could write these values to the MMR space.
Is this an acceptable way of using the firmware interface? My research
so far doesn't see the interface used this way and looking for your
I think this would be an entirely reasonable use of request_firmware().
