Host driver can't get a hint of DDR mode through ios->ddr flag anymore.
ios->timing is currently used to inform DDR mode as a substitute.
And capability of MMC_CAP_MMC_HIGHSPEED is added for DDR support.

request_any_context_irq now performs this internally. Remove the exra
calls from the driver so that request_any_context_irq succeeds.

pointed out that it was a little silly forcing every board or driver
to gpio_request() a GPIO that is later converted to an IRQ, and passed
to request_irq. The first patch in this series instead makes the core

Many IRQs are associated with GPIO pins. When the pin is used as an IRQ,
it can't be used as anything else; it should be requested. Enhance the
core interrupt code to call gpio_request() and gpio_direction_input() for
any IRQ that is also a GPIO. This prevents duplication of these calls in
each dri

mmc_sd_init_uhs_card function sets the driver type, current limit
and bus speed mode on card as well as on host controller side.
Currently bus speed mode is set by sending CMD6 to card and
immediately setting the timing mode in host controller. But
then before initiating tuning sequence, it also t

The wl1271 daughter card for AM18x EVMs is a combo wireless connectivity
add-on card, based on the LS Research TiWi module with Texas
Instruments' wl1271 solution.
It is a 4-wire, 1.8V, embedded SDIO WLAN device with an external IRQ
line and is power-controlled by a GPIO-based fixed regulator.
