* Rename struct device_d to deviceSascha Hauer2023-01-101-1/+1
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* gpio: Fix gpio commands called without -d optionSascha Hauer2022-09-281-2/+2
| | | | | | | | | 04443dc5fc breaks the calculation of arguments needed which effectively makes the -d option mandatory. Fix this.

* commands: gpio: add -d argument to set/get commandsAhmad Fatoum2022-09-131-10/+41
| | | | | | | | | | | | | | | | For debugging, it can be useful to reference GPIOs relative to a controller, e.g.: gpio_direction_output -d gpio4 20 1 instead of calculating the global gpio number. Extend the GPIO functions to support that. The argument to -d may be either a device name, a full path to a device tree node or an alias as in the example above.

* commands/*: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-04-271-12/+1
| | | | | | | | | | | | | While at it also drop references to the non-existing CREDITS file and do some small rearrangements for some uniform formatting. (SPDX-License-Identifier first, then copyright texts and then an empty line.) The advantage is that these specifiers are machine-parseable which helps license conformance.

* gpio: Introduce GPIO namesSascha Hauer2019-11-271-1/+3
| | | | | | | | | | | This introduces GPIO names. So far we only have labels which are given by the requester. In contrast names are given by the provider and do not change depending on whoever requests a GPIO. The gpio commands now also accept to reference a GPIO by name. The printing of the gpioinfo command is adjusted to nicely print both the label and the name. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* commands: gpio: Use kstrtoint() instead of simple_strtoul()Andrey Smirnov2018-10-291-3/+6
| | | | | | | | | | | | | | | | | | Use kstrtoint() instead of simple_strtoul() in order to properly handle invalid arguments. Current code using simple_strtoul() results in following: barebox@ZII RDU2 Board:/ gpio_get_value foo barebox@ZII RDU2 Board:/ echo $? 0 whereas with this patch we get: barebox@ZII RDU2 Board:/ gpio_get_value foo gpio_get_value: Invalid argument Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* commands: harmonize in-barebox documentationHolger Schurig2014-05-141-28/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does probably too much, but it's hard (and very cumbersome/time consuming) to break it out. What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* commands: group 'help' outputHolger Schurig2014-05-141-0/+4
| | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...
