[PATCH v1] uio: dfl: add IOPLL user-clock feature id

From: Peter Colberg
Date: Wed Aug 17 2022 - 17:38:30 EST


Add a Device Feature List (DFL) feature id for the configurable
IOPLL user clock source, which can be used to configure the clock
speeds that are used for RTL logic that is programmed into the
Partial Reconfiguration (PR) region of an FPGA.

The DFL feature id table can be found at:
https://github.com/OPAE/dfl-feature-id
