* fpga: Explicitly include correct DT includesRob Herring2023-07-171-1/+1
| | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

* fpga: bridge: Use standard dev_release for class driverRuss Weight2021-11-281-8/+4
| | | | | | | | | | | | | The FPGA bridge 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() function.

* fpga: bridge: add devm_fpga_bridge_createAlan Tull2018-10-161-5/+3
| | | | | | | | | | | | | Add devm_fpga_bridge_create() which is the managed version of fpga_bridge_create(). Change current bridge drivers to use devm_fpga_bridge_create().

* fpga: bridge: change api, don't use drvdataAlan Tull2018-05-251-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: socfpga: fpga bridge driver supportAlan Tull2016-11-101-0/+180
Supports Altera SOCFPGA bridges: * fpga2sdram * fpga2hps * hps2fpga * lwhps2fpga Allows enabling/disabling the bridges through the FPGA Bridge Framework API functions. The fpga2sdram driver only supports enabling and disabling of the ports that been configured early on. This is due to a hardware limitation where the read, write, and command ports on the fpga2sdram bridge can only be reconfigured while there are no transactions to the sdram, i.e. when running out of OCRAM before the kernel boots. Device tree property 'init-val' configures the driver to enable or disable the bridge during probe. If the property does not exist, the driver will leave the bridge in its current state.
