Subject: [PATCH v2 0/6] Enhance definition of DFH and use enhancements for uart driver

From: Matthew Gerlach <matthew.gerlach@...el.com>

This patchset enhances the definition of the Device Feature Header (DFH) used by
the Device Feature List (DFL) bus and then uses the new enhancements in a uart
driver.

Patch 1 updates the DFL documentation to provide the motivation behind the 
enhancements to the definition of the DFH.

Patch 2 moves some of the DFH definitions to include/linux/dfl.h so that
they can be accessed by drivers outside of drivers/fpga.

Patch 3 adds the definitions for DFHv1.

Patch 4 defines and uses a DFHv1 parameter to provide a generic mechanism for
describing MSIX interrupts used by a particular feature instance.

Patch 5 gets the location and size of the feature's register set from DFHv1.

Patch 6 adds a DFL uart driver that makes use of the new features of DFHv1.

Basheer Ahmed Muddebihal (2):
  fpga: dfl: Move the DFH definitions
  fpga: dfl: Add DFHv1 Register Definitions

Matthew Gerlach (4):
  Documentation: fpga: dfl: Add documentation for DFHv1
  fpga: dfl: add generic support for MSIX interrupts
  fpga: dfl: parse the location of the feature's registers from DFHv1
  tty: serial: 8250: add DFL bus driver for Altera 16550.
