* fpga: fix for coding style issuesNava kishore Manne2022-05-101-3/+3
| | | | | | | | | | fixes the below checks reported by checkpatch.pl: - Lines should not end with a '(' - Alignment should match open parenthesis Signed-off-by: Nava kishore Manne <nava.manne@xilinx.com> Link: https://lore.kernel.org/r/20220423170235.2115479-3-nava.manne@xilinx.com Signed-off-by: Xu Yilun <yilun.xu@intel.com>
* fpga: region: Use standard dev_release for class driverRuss Weight2021-11-281-9/+27
| | | | | | | | | | | | | | | | | | The FPGA region 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 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.

* fpga: add devm_fpga_region_createAlan Tull2018-10-161-0/+4
| | | | | | | | | | | | | Add devm_fpga_region_create() which is the managed version of fpga_region_create(). Change current region drivers to use devm_fpga_region_create().

* fpga: region: add compat_id supportWu Hao2018-07-151-0/+2
| | | | | | | | | | | | This patch introduces a compat_id pointer member and sysfs interface for each fpga region, similar as compat_id for fpga manager, it allows applications to read the per region compat_id for compatibility checking before other actions on this fpga-region (e.g. PR).

* fpga: use SPDXAlan Tull2018-05-251-0/+2

* fpga: region: change api, add fpga_region_create/freeAlan Tull2018-05-251-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | 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: add attribute groupsAlan Tull2017-11-281-0/+2
| | | | | | | | | | | | Make it easy to add attributes to low level FPGA drivers the right way. Add attribute groups pointers to structures that are used when registering a manager, bridge, or group. When the low level driver registers, set the device attribute group. The attributes are created in device_add.

* fpga: region: add fpga_region_class_findAlan Tull2017-11-281-1/+4
| | | | | | | | | | | | Add a function for searching the fpga-region class. This will be useful when device tree code is no longer in the same file that declares the fpga-region class. Another step in separating common FPGA region code from device tree support.

* fpga: region: add register/unregister functionsAlan Tull2017-11-281-0/+7
| | | | | | | | | | | | | | | | Another step in separating common code from device tree specific code for FPGA regions. * add FPGA region register/unregister functions. * add the register/unregister functions to the header * use devm_kzalloc to alloc the region. * add a method for getting bridges to the region struct * add priv to the region struct * use region->info in of_fpga_region_get_bridges Signed-off-by: Alan Tull <atull@kernel.org> Acked-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* Create fpga-region.h. * Export fpga_region_program_fpga. * Move struct fpga_region and other things to the header. This is a step in separating FPGA region common code from Device Tree support.
