This is a complete rewrote of the original patch "MIPS: BCM47xx: use
gpiolib"
Instead of providing the GPIO driver in the arch code it is now moved
into ssb and bcma and could also be used by other systems. The GPIO
functions in drivers/ssb/embedded.c are still used by arch/mips/bcm47xx
/wgt634u.c, but I am planing to write some code for baord detection and
a driver for LED and the buttons, after that wgt634u.c could be removed.
This is based on mips/master tree.
v3:
* make BCMA_DRIVER_GPIO and SSB_DRIVER_GPIO selectable in Kconfig
* return -ENOTSUPP if the gpio driver is not activated
* handle error -ENOTSUPP with debug message
* do not lock *_gpio_in()
* add comment above chip->base = 0
v2:
* fix compile problem in ssb: add GPIO driver
Hauke Mehrtens (8):
bcma: add locking around GPIO register accesses
bcma: add bcma_chipco_gpio_pull{up,down}
bcma: add comment to bcma_chipco_gpio_control
bcma: add GPIO driver
ssb: add ssb_chipco_gpio_pull{up,down}
ssb: add locking around gpio register accesses
ssb: add GPIO driver
MIPS: BCM47XX: remove GPIO driver
