2019-07-30T11:07:41+00:00

Introduce wrappers for {bus/driver/class}_find_device() to locate devices by its of_node.

fpga: bridge: add devm_fpga_bridge_create

2018-10-16T09:13:50+00:00

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

fpga: bridge: fix obvious function documentation error

2018-09-30T15:49:55+00:00

fpga_bridge_dev_match() returns a FPGA bridge struct, not a FPGA manager struct so s/manager/bridge/. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: clarify that unregister functions also free

2018-05-25T16:23:56+00:00

The following functions also free the struct. Add that fact to the function documentation. - fpga_mgr_free - fpga_bridge_free - fpga_region_free Signed-off-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

fpga: bridge: kernel-doc fixes

2018-05-25T16:23:56+00:00

Fix the following warnings when documentation is built: ./drivers/fpga/fpga-bridge.c:143: warning: Function parameter or member 'info' not described in 'fpga_bridge_get' ./drivers/fpga/fpga-bridge.c:1: warning: no structured comments found Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: use SPDX

2018-05-25T16:23:56+00:00

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: bridge: change api, don't use drvdata

2018-05-25T16:23:55+00:00

Change fpga_bridge_register to not set drvdata. This is to support the case where a PCIe device can have more than one bridge. Add API functions to create/free the fpga bridge struct. Change fpga_bridge_register/unregister to take FPGA bridge struct as the only parameter. struct fpga_bridge *fpga_bridge_create(struct device *dev, const char *name, const struct fpga_bridge_ops *br_ops, void *priv); void fpga_bridge_free(struct fpga_bridge *br); int fpga_bridge_register(struct fpga_bridge *br); void fpga_bridge_unregister(struct fpga_bridge *br); Update the drivers that call fpga_bridge_register with the new API.

fpga: fpga-bridge: remove unnecessary null check in of_fpga_bridge_get

2017-11-28T15:31:27+00:00

Notice that bridge = to_fpga_bridge(dev); expands to: bridge = container_of(dev, struct fpga_bridge, dev); and container_of is never null, so this null check is unnecessary.

fpga: add attribute groups

2017-11-28T15:30:38+00:00

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: bridge: support getting bridge from device

2017-11-28T15:30:36+00:00

Add two functions for getting the FPGA bridge from the device rather than device tree node. This is to enable writing code that will support using FPGA bridges without device tree. Rename one old function to make it clear that it is device tree-ish. This leaves us with 3 functions for getting a bridge: * fpga_bridge_get Get the bridge given the device. * fpga_bridges_get_to_list Given the device, get the bridge and add it to a list. * of_fpga_bridges_get_to_list Renamed from priviously existing fpga_bridges_get_to_list. Given the device node, get the bridge and add it to a list. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman
