	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.

2019-10-04	staging: wfx: add infrastructure for new driver	Jérôme Pouiller
	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.
