dm: core: Provide ofnode_name_eq_unit() to accept a unit address

2025-01-22T23:08:24Z

When a unit-address is provided, use it to match against the node name. Since this increases code size, put it into a separate function. Signed-off-by: Simon Glass

dm: core: Clarify behaviour of ofnode_name_eq()

2025-01-22T23:08:23Z

This function is somewhat ambiguous, so expand the comments and add a test for the undefined behaviour. Signed-off-by: Simon Glass

dm: Add dm_remove_devices_active() for ordered device removal

2024-11-24T21:41:28Z

This replaces dm_remove_devices_flags() calls in all boot implementations to ensure non vital devices are consistently removed first. All boot implementation except arch/arm/lib/bootm.c currently just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result in crashes when dependencies between devices exists. The driver model's design document describes DM_FLAG_VITAL as "indicates that the device is 'vital' to the operation of other devices". Device removal at boot should follow this. Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which does this. Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI boot. The xhci-pci (driver which depends on the IOMMU to work) removes its mapping on removal. This explodes when the IOMMU device was removed first. dm_remove_devices_flags() is kept since it is used for testing of device_remove() calls in dm. Signed-off-by: Janne Grunau

dm: core: Add a function to see if a device exists

2024-11-04T03:27:12Z

All the uclass functions for finding a device end up creating a uclass if it doesn't exist. Add a function which instead returns NULL in this case. This is useful when in the 'unbind' path, since we don't want to undo any unbinding which has already happened. Signed-off-by: Simon Glass

test: Drop the blank line before test macros

2024-08-27T00:51:49Z

Most tests don't have this. It helps to keep the test declaration clearly associated with the function it relates to, rather than the next one in the file. Remove the extra blank line and mention this in the docs. Signed-off-by: Simon Glass

test: Rename unit-test flags

2024-08-27T00:51:48Z

The UT_TESTF_ macros read as 'unit test test flags' which is not right. Rename to UTF ('unit test flags'). This has the benefit of being shorter, which helps keep UNIT_TEST() declarations on a single line. Give the enum a name and reference it from the UNIT_TEST() macros while we are here.

dm: use list_count_nodes() for counting list nodes

2024-07-31T07:54:53Z

The linux kernel has the list_count_nodes() API functions which is used for counting nodes of a list. This has now been imported in U-Boot as part of an earlier commit. Use this function and drop the list_count_items(). Signed-off-by: Sughosh Ganu Reviewed-by: Simon Glass Reviewed-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas

global_data.h: drop write-only field dm_root_f

2024-07-03T06:36:33Z

The dm_root_f field seems to be entirely write-only and hence redundant, unless 'git grep' fails to find some access generated via preprocessor token concatenation or similar. Signed-off-by: Rasmus Villemoes Reviewed-by: Simon Glass

Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03Z

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 Signed-off-by: Tom Rini

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

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. Reported-by: Jonas Karlman Signed-off-by: Tom Rini
