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.

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.
