+ *
+ * Note: the brcmfmac can be loaded as module or be statically built-in into
+ * the kernel. 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.
