generic: remove brcmfmac-sdio.h
This file is present in the kernel so no point overlaying it.

If built-in then do note that it uses module_init (and - * module_exit) routines which equal device_initcall. So if you intend to - * create a module with the platform specific data for the brcmfmac and have - * it built-in to the kernel then use a higher initcall then device_initcall - * (see init.h). If this is not done then brcmfmac will load without problems - * but will not pickup the platform data. - * - * When the driver does not "detect" platform driver data then it will continue - * without reporting anything and just assume there is no data needed. Which is - * probably true for most platforms. - * - * Explanation of the platform_data fields: - * - * drive_strength: is the preferred drive_strength to be used for the SDIO - * pins. If 0 then a default value will be used. This is the target drive - * strength, the exact drive strength which will be used depends on the - * capabilities of the device. - * - * oob_irq_supported: does the board have support for OOB interrupts. SDIO - * in-band interrupts are relatively slow and for having less overhead on - * interrupt processing an out of band interrupt can be used. If the HW - * supports this then enable this by setting this field to true and configure - * the oob related fields. - * - * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are - * used for registering the irq using request_irq function. - * - * power_on: This function is called by the brcmfmac when the module gets - * loaded. This can be particularly useful for low power devices. The platform - * spcific routine may for example decide to power up the complete device. - * If there is no use-case for this function then provide NULL. - * - * power_off: This function is called by the brcmfmac when the module gets - * unloaded. At this point the device can be powered down or otherwise be reset. - * So if an actual power_off is not supported but reset is then reset the device - * when this function gets called. This can be particularly useful for low power - * devices. If there is no use-case for this function (either power-down or - * reset) then provide NULL. - * - * reset: This function can get called if the device communication broke down. - * This functionality is particularly useful in case of SDIO type devices. It is - * possible to reset a dongle via sdio data interface, but it requires that - * this is fully functional. This function is chip/module specific and this - * function should return only after the complete reset has completed. - */ - -#define BRCMFMAC_SDIO_PDATA_NAME "brcmfmac_sdio" - -struct brcmfmac_sdio_platform_data { - unsigned int drive_strength; - bool oob_irq_supported; - unsigned int oob_irq_nr; - unsigned long oob_irq_flags; - void (*power_on)(void); - void (*power_off)(void); - void (*reset)(void); -}; - -#endif /* _LINUX_BRCMFMAC_PLATFORM_H */ |
