[PATCH v10 0/8] FPGA Manager Framework and Simple FPGA Bus

[atull]

From: Alan Tull <atull@xxxxxxxxxxxxxxxxxxxxx>

This patchset adds two chunks plus documentation:
 * fpga manager core: exports API functions that write an image to a FPGA
 * DT Overlay support: simple-fpga-bus to handle FPGA from a DT overlay

The fpga manager core is mature enough to be in the regular kernel.

simple-fpga-bus is proposed for staging.

Changes from v9:
 * Move fpga manager core to drivers/fpga
 * Move simple-fpga-bus to staging/simple-fpga-bus
 * add TODO
 * Improvements in fpga_manager_get/put (call module_try_get)
 * Add flags parameter to .write_complete ops as requested
 * Documentation improvements
 * Other minor cleanup

More info:

The core's API is minimal to start with: only 6 functions.  This gives a
manufacturer-agnostic interface for programming FPGA's such that higher
level interfaces (such as DT Overlays) can be shared.

The DT Overlays support exists for the usage where the FPGA will contain
some "hardware" that will need drivers.  Where that use model is not
appealing, the core API can be used to add a different interface.

The bindings for the socpfga fpga manager already are upstreamed as

The core FPGA manager support is standalone.  The DT Overlays support
is dependent on Pantelis's dtc overlay patches from
https://github.com/pantoniou/dtc.git
and his DT overlays configfs interface patches and fixes from
https://github.com/pantoniou/linux-beagle-track-mainline
