668761ac01 brcmfmac: define and use platform specific data for SDIO.
This patch adds support for platform specific data for SDIO
fullmac devices. Currently OOB interrupts are configured by Kconfig
BRCMFMAC_SDIO_OOB but that is now determined dynamically by checking
availibility of platform data.

4a3da9906b brcmfmac: support save&restore firmware feature
Save & restore is an advanced power saving feature,
supported only on selected devices.
SR operation is almost completely transparent to the driver.
Support for it is hardware and firmware dependent.

4531603a7a brcmfmac: clear status for in-band interrupt in brcmf_sdbrcm_isr
SDIO in-band interrupt is level sensitive according to SDIO standard.
When the register interrupt handler gets called by SDIO stack it is
running in non interrupt context and expected to clear the interrupt
from the dongle. Therefore in-band and out-of-band interrupt need to
be handled differently.

ba89bf1961 brcmfmac: add out of band interrupt support
Some sdio host controllers do not support real in band interrupt.
Software polling mode as a replacement is not fast enough for
high throughput and new features. Also some in band interrupts
do not support host wake up on embedded platform even when they
are real physical interrupts. Therefore out of band (oob)
interrupt mechanism is implemented for these scenarios.

To provide oob irq number and flags used for irq registration in
brcmfmac, a platform device contains irq resource must be
registered in board specific code.

Here is an example of platform device structure:
struct resource brcmf_sdio_res[] = {
	{
		.start	= GPIO_BRCMF_SDIO_OOB_NUM,
		.end	= GPIO_BRCMF_SDIO_OOB_NUM,
		.flags  = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
	}
};
struct platform_device brcmf_sdio_device = {
	.name		= "brcmf_sdio_pd",
	.id		= -1,
	.num_resources	= ARRAY_SIZE(brcmf_sdio_res),
	.resource	= brcmf_sdio_res,
};

d76d1c8c1d brcm80211: fmac: save bus interface structure in function 2 device
bus interface was stored in sdio card device. The device pointer
is used as parameter of interface functions between common layer
and bus layer to make the function declaration generic for different
bus type. But the card device is a parent device layer for SDIO
function devices. It doesn't contain all contexts needed by udev.
This patch moves the shared structure to private driver data pointer
of SDIO function 2 device which is more appopriate for net device
and cfg80211 registration.
