2020-04-29	fpga: machxo2-spi: Use new structure for SPI transfer delays	Sergiu Cuciurean	1	-4/+8
	In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

2018-10-16	fpga: mgr: add devm_fpga_mgr_create	Alan Tull	1	-8/+3
	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 <atull@kernel.org> Suggested-by: Federico Vaga <federico.vaga@cern.ch> Acked-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-05-25	fpga: manager: change api, don't use drvdata	Alan Tull	1	-4/+16
	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.
