2022-04-06T06:52:14Z

The wfx driver is now mature enough to leave the staging area. Signed-off-by: Jérôme Pouiller Signed-off-by: Kalle Valo

staging: wfx: do not probe the device if not in the DT

2022-01-25T15:19:42Z

Since the WF200 VID/PID are not reliable, it's recommended to declare it in the DT. Until now, if the device was not declared, the driver just printed a warning and continue. But, the risk of a collision is too high, the driver now returns an error.

staging: wfx: fix Makefile and Kconfig licenses

2022-01-25T15:19:40Z

License was missing in Kconfig. Makefile license was GPL-2.0 while rest of the driver use GPL-2.0-only. Signed-off-by: Jérôme Pouiller Link: https://lore.kernel.org/r/20220113085524.1110708-2-Jerome.Pouiller@silabs.com Signed-off-by: Greg Kroah-Hartman

staging: wfx: fix CONFIG_MMC=m with CONFIG_WFX=y

2019-10-26T18:42:32Z

If CONFIG_MMC=m and CONFIG_WFX=y, compilation complains with undefined references: drivers/staging/wfx/main.o: In function `wfx_core_init': /linux/drivers/staging/wfx/main.c:488: undefined reference to `sdio_register_driver' drivers/staging/wfx/main.o: In function `wfx_core_exit': /linux/drivers/staging/wfx/main.c:496: undefined reference to `sdio_unregister_driver' drivers/staging/wfx/main.o:(.debug_addr+0x1a8): undefined reference to `sdio_register_driver' drivers/staging/wfx/main.o:(.debug_addr+0x6f0): undefined reference to `sdio_unregister_driver' Indeed, symbols sdio_* are not present in kernel image. This patch disallows CONFIG_WFX=y if CONFIG_MMC=m. This solution impacts users who want to use SPI bus with configuration: CONFIG_WFX=y + CONFIG_SPI=y + CONFIG_MMC=m. However, I think this is a twisted case. So, I think it won't be missed.

staging: wfx: add infrastructure for new driver

2019-10-04T08:26:51Z

Instantiate build infrastructure WFx driver. This driver provides support for Wifi chipset Silicon Labs WF200 and further: https://www.silabs.com/documents/public/data-sheets/wf200-datasheet.pdf This chip support SPI and SDIO bus. SDIO interface has two particularities: 1. Some parameters may be useful for end user (I will talk about gpio_wakeup later). 2. The SDIO VID and PID of WF200 are 0000:0001 which are too much generic to rely on. So, current code checks VID/PID and looks for a node in DT (since WF200 targets embedded platforms, I don't think it is a problem to rely on DT). DT can also be used to define to parameters for driver. Currently, if no node is found, a warning is emitted, but it could be changed in error.
