u-boot.git/common/cmd_gpio.c, branch v2012.04 Unnamed repository; edit this file 'description' to name the repository. Convert cmd_usage() calls in common to use a return value 2012-03-06T20:09:46+00:00 Simon Glass sjg@chromium.org 2011-12-10T08:44:01+00:00 4c12eeb8b55483e48ef98b8a480e2bbacc9f210d 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.

gpio: generalize for all generic gpio providers 2011-04-13T19:56:51+00:00 Mike Frysinger vapier@gentoo.org 2011-04-03T08:40:46+00:00 a972b8d701814317be2b8bcca4103f37bcbb467c 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.
