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 */ diff --git a/include/linux/platform_data/clk-lpss.h b/include/linux/platform_data/clk-lpss.h new file mode 100644 index 00000000000..528e73ce46d --- /dev/null +++ b/include/linux/platform_data/clk-lpss.h @@ -0,0 +1,18 @@ +/* + * Intel Low Power Subsystem clocks. + * + * Copyright (C) 2013, Intel Corporation + * Authors: Mika Westerberg <mika.westerberg@linux.intel.com> + * Rafael J.
