Subject: [PATCH 1/2] include: fpga: adi-axi-common.h: add definitions for supported FPGAs
Date:   Wed, 10 Feb 2021 12:15:34 +0200

From: Mircea Caprioru <mircea.caprioru@analog.com>

All (newer) FPGA IP cores supported by Analog Devices, store information in
the synthesized designs. This information describes various parameters,
including the family of boards on which this is deployed, speed-grade, and
so on.

Currently, some of these definitions are deployed mostly on Xilinx boards,
but they have been considered also for FPGA boards from other vendors.

The register definitions are described at this link:
  https://wiki.analog.com/resources/fpga/docs/hdl/regmap
(the 'Base (common to all cores)' section).

This is a continuation of this old set:
https://lore.kernel.org/linux-clk/20200929144417.89816-1-alexandru.ardelean@analog.com/

Particularly patches:
  https://lore.kernel.org/linux-clk/20200929144417.89816-15-alexandru.ardelean@analog.com/
  https://lore.kernel.org/linux-clk/20200929144417.89816-16-alexandru.ardelean@analog.com/

That was v4, but this patchset was split away from it, to resolve
discussion on some other patches in that set.

The other patches were accepted here:
