fpga: add devm_fpga_region_create

2018-10-16T09:13:50Z

Add devm_fpga_region_create() which is the managed version of fpga_region_create(). Change current region drivers to use devm_fpga_region_create(). Signed-off-by: Alan Tull Suggested-by: Federico Vaga Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: region: add compat_id support

2018-07-15T11:55:44Z

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 SPDX

2018-05-25T16:23:56Z

Replace GPLv2 boilerplate with SPDX in FPGA code that came from me or from Altera. Signed-off-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

fpga: region: change api, add fpga_region_create/free

2018-05-25T16:23:56Z

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 groups

2017-11-28T15:30:38Z

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. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: region: add fpga_region_class_find

2017-11-28T15:30:38Z

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. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: region: add register/unregister functions

2017-11-28T15:30:38Z

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 Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: region: add fpga-region.h header

2017-11-28T15:30:38Z

* 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. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman
