Simplify registration using new devm_fpga_mgr_register() API. Reviewed-by: Tom Rix <[email protected]> Signed-off-by: Moritz Fischer <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2020-04-29fpga: ice40-spi: Use new structure for SPI transfer delaysSergiu Cuciurean1-2/+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).

2018-10-16fpga: mgr: add devm_fpga_mgr_createAlan Tull1-7/+3
Add devm_fpga_mgr_create() which is the managed version of fpga_mgr_create().

2018-05-25fpga: manager: change api, don't use drvdataAlan Tull1-4/+17
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.
