Russ Weight 4ba0b2c294 fpga: mgr: Use standard dev_release for class driver
The FPGA manager class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes
the managed resource code for the freeing of the class data structure
and combines the create() and register() functions into a single
register() or register_full() function.

The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

The devm_fpga_mgr_register() function is retained, and the
devm_fpga_mgr_register_full() function is added.

Tom Rix b02a40713d fpga: fpga-mgr: wrap the state() op
An FPGA manager should not be required to provide a state() op.
Add a wrapper consistent with the other op wrappers.
Move op check to wrapper.
Default to FPGA_MGR_STATE_UNKNOWN, what noop state() ops use.
Remove unneeded noop state() ops

Alan Tull 7085e2a94f fpga: manager: change api, don't use drvdata
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.

Florian Fainelli 4348f7e2ae FPGA: Add TS-7300 FPGA manager
Add support for loading bitstreams on the Altera Cyclone II FPGA
populated on the TS-7300 board. This is done through the configuration
and data registers offered through a memory interface between the EP93xx
SoC and the FPGA via an intermediate CPLD device.

The EP93xx SoC on the TS-7300 does not have direct means of configuring
the on-board FPGA other than by using the special memory mapped
interface to the CPLD. No other entity on the system can control the
FPGA bitstream.
