+Subject: [PATCH] brcmfmac: switch to new platform data
|
|
|
+
|
|
|
+Platform data is only available for sdio. With this patch a new
|
|
|
+platform data structure is being used which allows for platform
|
|
|
+data for any device and configurable per device. This patch only
|
|
|
+switches to the new structure and adds support for SDIO devices.

|
|
+- * the kernel. If built-in then do note that it uses module_init (and

|
|
|
+- * 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
|
|
|

+- * 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.
|
|
|
+- *
|
|
|
+- * broken_sg_support: flag for broken sg list support of SDIO host controller.
|
|
|
+- * Set this to true if the SDIO host controller has higher align requirement
|
|
|
+- * than 32 bytes for each scatterlist item.
|
|
|
+- *
|
|
|
+- * sd_head_align: alignment requirement for start of data buffer
|
|
|
+- *
|
|
|
+- * sd_sgentry_align: length alignment requirement for each sg entry
|
|
|
+- *
|
|
|
+- * 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.

++ * @power_on: This function is called by the brcmfmac driver 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 devices can be powered down or
|
|
|
++ * otherwise be reset. So if an actual power_off is not supported
|
|
|
++ * but reset is supported by the devices then reset the devices
|
|
|
++ * when this function gets called. This can be particularly useful
|
|
|
++ * for low power devices. If there is no use-case for this
|
|
|
++ * function then provide NULL.
