Mike Frysinger	95b4b9d97a	Blackfin: gpio: optimize free path a little ... When we aren't doing resource tracking, the gpio_free() function is a stub that simply returns, so pull this logic up a level and make it an inline stub in the header. Now we don't have to waste time at any of the call sites. Signed-off-by: Mike Frysinger <vapier@gentoo.org>	2011-07-12 02:17:45 -04:00
Mike Frysinger	a972b8d701	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.

Mike Frysinger	4638b21f2e	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.
