* cmd_led: Extend led command to support blinking and more ledsStefan Roese2015-04-23-10/+38
| | | | | | | | | | | This patch extends the U-Boot "led" command to support automatic blinking by setting a blink frequency in milliseconds. Additionally the number of supported LEDs is increased to 6 (0...5). This will be used by the PCA9551 LED driver. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>

* led: Use STATUS_LED_ON and STATUS_LED_OFF when calling __led_setOtavio Salvador2013-03-07-2/+4
| | | | | | | This fixes the gpio_led driver which needs to compare againt a STATUS_LED_ON to enable a led. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
* cmd_led.c: Standardize format of help and usage info.Robert P. J. Day2012-12-06-3/+3
| | | | | | | Current "led" help and usage info has redundancy and extraneous newlines, tweak it to be consistent with other commands. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca>
* Convert cmd_usage() calls in common to use a return valueSimon Glass2012-03-06-3/+3
| | | | | | | | | 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.

This patch allows any board implementing the coloured LED API to control the LEDs from the console. led [green | yellow | red | all ] [ on | off ] or led [ 1 | 2 | 3 | all ] [ on | off ] Adds configuration item CONFIG_CMD_LED enabling the command. Partially based on patch from Ulf Samuelsson: http://www.mail-archive.com/u-boot@lists.denx.de/msg09593.html. Updated based on feedback: http://www.mail-archive.com/u-boot@lists.denx.de/msg41847.html https://groups.google.com/d/topic/beagleboard/8Wf1HiK_QBo/discussion * Fixed a handful of style issues. * Significantly reduced the number of #ifdefs and redundant code * Converted redundant code into loops test against a structure * Made use of cmd_usage() * Introduced a str_onoff() function, but haven't yet put it in common * Eliminated trailing newline Signed-off-by: Jason Kridner <jkridner@beagleboard.org> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
