2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2023-10-16cmd: gpio: Skip output on -ENOENTPaul Barker
On the Renesas RZ/G2L SoC family, valid GPIO numbers are not contiguous. This is determined by the device tree, where a fixed number of bits are used for the 'pin' number within a 'port', even though not all ports have the same number of pins. The device tree can't be changed here without breaking backwards compatibility in Linux, which we don't want to do. To avoid printing a status for each of these invalid GPIO numbers when a user executes `gpio status -a`, we allow gpio_get_function() to return -ENOENT when the given offset does not refer to a valid GPIO pin and we skip printing anything if this occurs.

2022-10-17cmd: List all uclass devices regardless of probe errorMichal Suchanek
There are a few commands that iterate uclass with uclass_first_device/uclass_next_device or the _err variant. Use the _check class iterator variant to get devices that fail to probe as well, and print the status. Signed-off-by: Michal Suchanek <msuchanek@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org>
2022-04-20cmd: gpio: Add `gpio read` subcommandDiego Rondini
As explained in commit 4af2a33ee5b9 ("cmd: gpio: Make `gpio input` return pin value again") the `gpio input` is used in scripts to obtain the value of a pin, despite the fact that CMD_RET_FAILURE is indistinguishable from a valid pin value. To be able to detect failures and properly use the value of a GPIO in scripts we introduce the `gpio read` command that sets the variable `name` to the value of the pin. Return code of the `gpio read` command can be used to check for CMD_RET_SUCCESS or CMD_RET_FAILURE. CONFIG_CMD_GPIO_READ is used to enable the `gpio read` command.

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-03-13cmd: gpio: Make `gpio input` return pin value againAlex Kiernan
4dbc107f4683 ("cmd: gpio: Correct do_gpio() return value") correctly changed the behaviour of the gpio command to return CMD_RET_SUCCESS or CMD_RET_FAILURE, but any existing script which expects the return value to be the pin value is broken by this change. Reinstate the legacy behaviour for `gpio input` only.

2020-02-07cmd: gpio: Correct do_gpio() return valueLuka Kovacic
Use the correct return value in function do_gpio() and update commands documentation with the return values from command_ret_t enum. CMD_RET_SUCCESS is returned on command success and CMD_RET_FAILURE is returned on command failure. The command was returning the pin value, which caused confusion when debugging (#define DEBUG).

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2019-02-20gpio: Use case-insentive matching on the GPIO nameSimon Glass

2019-02-20gpio: Show inactive GPIOs when explicitly requestedSimon Glass
At present the gpio command only shows GPIOs which are marked as in use. This makes sense with 'gpio status' since we already have the '-a' flag to indicate that all GPIOs should be shown. But when a particular GPIO is requested, it seems better to always display it. At present the request is simply ignored. For example if GPIO a10 is not in use, then: > gpio status a10 shows nothing, not even the function being used for that GPIO. With this change, it shows the pin status: > gpio status a10 a10: input: 0 [ ] Add an extra parameter for this to avoid changing the existing flag parameter.
