* Change the fpga-mgr API to have one fpga_mgr_load function
instead of three.
* Separate common FPGA region code from Device Tree support
* Expose API functions for FPGA regions
* Add API functions for bridges where DT is not used.
* clean up drivers/fpga/Kconfig
* add attribute groups when registering a fpga manager, bridge, or region.
Needed because the current FPGA layer has a couple of problems:
* We now have 3 functions for programming a FPGA, depending on whether
the image is in a sg list, a buffer, or firmware. So upper layers
have to be written assuming where the image will be or will have to
write extra code to maintain flexibility.
* users who aren't using device tree are left to write their
own code that is essentially a rewrite of FPGA region.
v5 changes are small:
* add back in fpga_mgr_put in of_fpga_region_remove
* make __fpga_bridge_get static
* move #ifndef before #includes in headers
* Spelling fixes and other nits
Alan Tull (18):
fpga: bridge: support getting bridge from device
fpga: mgr: API change to replace fpga load functions with single
function
fpga: mgr: separate getting/locking FPGA manager
fpga: region: use dev_err instead of pr_err
fpga: region: remove unneeded of_node_get and put
fpga: region: get mgr early on
fpga: region: check for child regions before allocing image info
fpga: region: fix slow warning with more than one overlay
fpga: region: use image info as parameter for programming region
fpga: region: separate out code that parses the overlay
fpga: region: add fpga-region.h header
fpga: region: rename some functions prior to moving
fpga: region: add register/unregister functions
fpga: region: add fpga_region_class_find
fpga: region: move device tree support to of-fpga-region.c
fpga: of-fpga-region: accept overlays that don't program FPGA
fpga: clean up fpga Kconfig
fpga: add attribute groups
