Blackfin: import gpio/portmux layer from Linux The current pinmux handling has spread throughout Blackfin drivers and board code and is getting hideous to maintain. So import the gpio and portmux layer from the Blackfin Linux code. This should spur a serious of cleanups across the Blackfin tree. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

bfin: Move gpio support for bf54x and bf60x into the generic driver folder. The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx. A lot of machine macros are used to accomodate both code in one gpio driver. This patch split the old gpio driver and move new gpio2 support to the generic gpio driver folder. - To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's config header file. - The gpio2 driver supports bf54x, bf60x and future ADI processors, while the older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561. - All blackfin specific gpio function names are replaced by the generic gpio APIs.

gpio: generalize for all generic gpio providers The Blackfin gpio command isn't terribly Blackfin-specific. So generalize the few pieces into two new optional helpers: name_to_gpio() - turn a string name into a GPIO # gpio_status() - display current pin bindings (think /proc/gpio) Once these pieces are pulled out, we can relocate the cmd_gpio.c into the common directory.
