      docs: add some directories to the main documentation index · 113094f7
      Mauro Carvalho Chehab authored 
      
The contents of those directories were orphaned at the documentation
body.

While those directories could likely be moved to be inside some guide,
I'm opting to just adding their indexes to the main one, removing the
:orphan: and adding the SPDX header.

For the drivers, the rationale is that the documentation contains
a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on
separate directories, as we've be doing with similar subsystem-specific
docs that were not split yet.

For the others, well... I'm too lazy to do the move. Also, it
seems to make sense to keep at least some of those at the main
dir (like kbuild, for example). In any case, a latter patch
could do the move.

      documentation: fpga: move fpga-region.txt to driver-api · fcc80395
      Alan Tull authored 
      
Move Documentation/fpga/fpga-region.txt to
driver-api/fpga/fpga-region.rst.  Including:
 - Add it to driver-api/fpga/index.rst
 - Formatting changes to build cleanly as ReST documentation
 - Some rewrites for better flow as a ReST doc such as moving
   API reference to the end of the doc
 - Rewrite API reference section to refer to kernel-doc
   documentation in fpga-region.c driver code

      documentation: fpga: move fpga-mgr.txt to driver-api · 547b822c
      Alan Tull authored 
      
Move Documentation/fpga/fpga-mgr.txt to driver-api/fpga/fpga-mgr.rst
and:
 - Add to driver-api/fpga/index.rst
 - Format changes so documentation builds cleanly.
 - Minor rewrites that make the doc flow better as ReST documentation.
   - Such as moving API reference to end of doc
 - Change API reference section to refer to kernel-doc documentation in
   fpga-mgr.c driver code rather than statically defining each function.

      Documentation: fpga: move fpga overview to driver-api · 66c472cd
      Alan Tull authored 
      
Start of moving Documentation/fpga/*.txt to driver-api, including:
 - Add new directory driver-api/fpga
 - Add new file driver-api/fpga/index.rst
 - Add driver-api/fpga to driver-api/index.rst
 - Move Documentation/fpga/overview.txt to driver-api/fpga/intro.rst
 - Formatting and rewrites so that intro.rst will build cleanly
   and form a good introduction to the rest of the docs to be added.

      fpga: region: change api, add fpga_region_create/free · 9f368977
      Alan Tull authored 
      
Add fpga_region_create/free API functions.

Change fpga_region_register to take FPGA region struct as the only
parameter.  Change fpga_region_unregister to return void.

  struct fpga_region *fpga_region_create(struct device *dev,
                        struct fpga_manager *mgr,
                        int (*get_bridges)(struct fpga_region *));
  void fpga_region_free(struct fpga_region *region);
  int fpga_region_register(struct fpga_region *region);
  void fpga_region_unregister(struct fpga_region *region);

Remove groups storage from struct fpga_region, it's not
needed.  Callers can just "region->dev.groups = groups;"
after calling fpga_region_create.

Update the drivers that call fpga_region_register with the new API.

      fpga: manager: change api, don't use drvdata · 7085e2a9
      Alan Tull authored 
      
Change fpga_mgr_register to not set or use drvdata.  This supports
the case where a PCIe device has more than one manager.

Add fpga_mgr_create/free functions.  Change fpga_mgr_register and
fpga_mgr_unregister functions to take the mgr struct as their only
parameter.

  struct fpga_manager *fpga_mgr_create(struct device *dev,
                const char *name,
                const struct fpga_manager_ops *mops,
                void *priv);
  void fpga_mgr_free(struct fpga_manager *mgr);
  int fpga_mgr_register(struct fpga_manager *mgr);
  void fpga_mgr_unregister(struct fpga_manager *mgr);

Update the drivers that call fpga_mgr_register with the new API.

      fpga: mgr: separate getting/locking FPGA manager · ebf877a5
      Alan Tull authored 
      
Previously when the user gets a FPGA manager, it was locked
and nobody else could use it for programming.

This commit makes it straightforward to save a reference to an
FPGA manager and only lock it when programming the FPGA.

Add functions that get an FPGA manager's mutex for exclusive use:
* fpga_mgr_lock
* fpga_mgr_unlock

The following functions no longer lock an FPGA manager's mutex:
* of_fpga_mgr_get
* fpga_mgr_get
* fpga_mgr_put

      fpga: mgr: API change to replace fpga load functions with single function · 5cf0c7f6
      Alan Tull authored 
      
fpga-mgr has three methods for programming FPGAs, depending on
whether the image is in a scatter gather list, a contiguous
buffer, or a firmware file. This makes it difficult to write
upper layers as the caller has to assume whether the FPGA image
is in a sg table, as a single buffer, or a firmware file.
This commit moves these parameters to struct fpga_image_info
and adds a single function for programming fpgas.

New functions:
* fpga_mgr_load - given fpga manager and struct fpga_image_info,
   program the fpga.

* fpga_image_info_alloc - alloc a struct fpga_image_info.

* fpga_image_info_free - free a struct fpga_image_info.

These three functions are unexported:
* fpga_mgr_buf_load_sg
* fpga_mgr_buf_load
* fpga_mgr_firmware_load

Also use devm_kstrdup to copy firmware_name so we aren't making
assumptions about where it comes from when allocing/freeing the
struct fpga_image_info.

API documentation has been updated and a new document for
FPGA region has been added.
