Simon Glass	4c12eeb8b5	Convert cmd_usage() calls in common to use a return value ... Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly. I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

Mike Frysinger	6801201ee7	gpio: check request result ... Make sure the pin request passed before attempting to use it later on. Signed-off-by: Mike Frysinger <vapier@gentoo.org>	2011-04-13 15:57:00 -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.
