From: Matthew Gerlach <matthew.gerlach@intel.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.
