|

*
|
||||
* 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.
