dm: core: Correct the return value for uclass_find_first_device()

2019-10-08T05:57:38Z

This function returns -ENODEV when there is no device. This is inconsistent with other functions, such as uclass_find_next_device(), which returns 0. Update it and tidy up the incorrect '-1' values in the comments. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Tested-by: Bin Meng

dm: device: fail uclass_find_first_device() if list_empty

2019-02-09T12:51:00Z

While uclass_find_device() fails with -ENODEV in case of list_empty strangely uclass_find_first_device() returns 0. Fix uclass_find_first_device() to also fail with -ENODEV instead. Signed-off-by: Marcel Ziswiler Reviewed-by: Simon Glass

dm: core: Add a function to find the first inactive child

2018-10-09T10:40:27Z

Some devices have children and want to press an existing inactive child into service when needed. Add a function to help with this. Signed-off-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

dm: core: Add a function to look up a uclass by name

2018-02-03T17:08:40Z

Each uclass has a driver name which we can use to look up the uclass. This is useful for logging, where the uclass ID is used as the category. Add a function to handle this, as well as a test. Signed-off-by: Simon Glass

dm: test: Add test for device removal

2017-04-05T02:15:10Z

Add a test for the correct device removal. Currently two different ways for device removal are supported: - Normal device removal via the device_remove() API - Removal via selective device driver flags (DM_FLAG_ACTIVE_DMA) This new test "remove_active_dma" adds tests cases for those both ways of removal. This is done by adding a new test driver, which has this flag set. Signed-off-by: Stefan Roese Cc: Simon Glass

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10Z

This patch adds the flags parameter to device_remove() and changes all calls to this function to provide the default value of DM_REMOVE_NORMAL for "normal" device removal. This is in preparation for the driver specific pre-OS (e.g. DMA cancelling) remove support. Signed-off-by: Stefan Roese Cc: Simon Glass Acked-by: Simon Glass

test/dm/core.c: Make pre-reloc test use pre-reloc struct

dm: test: Show the amount of leaked memory on error

Adjust the memory leak tests to show the amount of memory leaked. This can be a useful signal as to what is wrong. Signed-off-by: Simon Glass

test: Generalize the unit test framework

2015-05-21T13:16:16Z

Separate the ability to define tests and assert status of test functions from the dm tests so they can be used more consistently throughout all tests. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass
