fpga: mgr: add devm_fpga_mgr_create

2018-10-16T09:13:50Z

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

docs: fpga: document fpga manager flags

2018-09-30T15:49:55Z

Add flags #defines to kerneldoc documentation in a useful place. Signed-off-by: Alan Tull Acked-by: Moritz Fischer Signed-off-by: Greg Kroah-Hartman

fpga: mgr: add compat_id support

2018-07-15T11:55:44Z

This patch introduces compat_id support to fpga manager, it adds a fpga_compat_id pointer to fpga manager data structure to allow fpga manager drivers to save the compatibility id. This compat_id could be used for compatibility checking before doing partial reconfiguration to associated fpga regions. Signed-off-by: Wu Hao Acked-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

fpga: mgr: add status for fpga-manager

2018-07-15T11:55:44Z

This patch adds status sysfs interface for fpga manager, it's a read only interface which allows user to get fpga manager status, including full/partial reconfiguration error and other status information. It adds a status callback to fpga_manager_ops too, allows each fpga_manager driver to define its own method to collect latest status from hardware. The following sysfs file is created: * /sys/class/fpga_manager//status Return status of fpga manager, including reconfiguration errors.

fpga: mgr: add region_id to fpga_image_info

2018-07-15T11:55:44Z

This patch adds region_id to fpga_image_info data structure, it allows driver to pass region id information to fpga-mgr via fpga_image_info for fpga reconfiguration function. Signed-off-by: Wu Hao Acked-by: Moritz Fischer Acked-by: Alan Tull Signed-off-by: Greg Kroah-Hartman

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: manager: change api, don't use drvdata

2018-05-25T16:23:55Z

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: 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: use image info as parameter for programming region

2017-11-28T15:30:37Z

Use FPGA image info (region->info) when region code is programming the FPGA to pass in multiple parameters. This is a baby step in refactoring the FPGA region code to separate out common FPGA region code from FPGA region Device Tree overlay support.

fpga: mgr: separate getting/locking FPGA manager

2017-11-28T15:30:37Z

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