dm: core: introduce uclass_get_device_by_of_path()

2023-04-28T17:48:59Z

There's quite a few instances of board-specific code doing off = fdt_path_offset(gd->fdt_blob, ...); ... ret = uclass_get_device_by_of_offset(..., off, &dev); looking for an eeprom or a pmic via some alias. Such code can be simplified a little if we have a helper for directly getting a device via device tree path (including being given as an alias). Implement it in terms of ofnode rather than raw offsets so that this will work whether live tree is enabled or not. Signed-off-by: Rasmus Villemoes

dm: core: Do not stop uclass iteration on error

2022-10-29T13:36:33Z

When probing a device fails NULL pointer is returned, and following devices in uclass list cannot be iterated. Skip to next device on error instead. With that the only condition under which these simple iteration functions return error is when the dm is not initialized at uclass_get time. This is not all that interesting, change return type to void. Fixes: 6494d708bf ("dm: Add base driver model support") Signed-off-by: Michal Suchanek Reviewed-by: Simon Glass

dm: core: Switch uclass__device_err to use uclass__device_check

2022-10-18T03:17:12Z

The _err variant iterators use the simple iterators without suffix as basis. However, there is no user that uclass_next_device_err for iteration, many users of uclass_first_device_err use it to get the first and (assumed) only device of an uclass, and a couple that use uclass_next_device_err to get the device following a known device in the uclass list. While there are some truly singleton device classes in which more than one device cannot exist these are quite rare, and most classes can have multiple devices even if it is not the case on the SoC's EVB. In a later patch the simple iterators will be updated to not stop on error and return next device instead. With this in many cases the code that expects the first device or an error if it fails to probe may get the next device instead. Use the _check iterators as the basis of _err iterators to preserve the old behavior. Signed-off-by: Michal Suchanek Reviewed-by: Simon Glass

dm: core: Rename and fix uclass_get_by_name_len()

2022-04-25T14:00:03Z

It seems that namelen is more common in U-Boot. Rename this function to fit in better. Also fix a bug where it breaks the operation of uclass_get_by_name() and add a test. Signed-off-by: Simon Glass Reported-by: Patrick Delaunay Reported-by: Tim Harvey
