of: unittest: Fix of_count_phandle_with_args() expected value message

2024-01-11T22:18:30+00:00

The expected result value for the call to of_count_phandle_with_args()
was updated from 7 to 8, but the accompanying error message was
forgotten.

of: Fix double free in of_parse_phandle_with_args_map

2024-01-09T18:54:02+00:00

In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

of: device: Export of_device_make_bus_id()

2023-12-15T12:30:07+00:00

This helper is really handy to create unique device names based on their
device tree path, we may need it outside of the OF core (in the NVMEM
subsystem) so let's export it. As this helper has nothing patform
specific, let's move it to of/device.c instead of of/platform.c so we
can add its prototype to of_device.h.

dma-mapping: don't store redundant offsets

2023-12-15T11:32:42+00:00

A bus_dma_region necessarily stores both CPU and DMA base addresses for
a range, so there's no need to also store the difference between them.

iommmu/of: Do not return struct iommu_ops from of_iommu_configure()

2023-12-12T09:18:47+00:00

Nothing needs this pointer. Return a normal error code with the usual
IOMMU semantic that ENODEV means 'there is no IOMMU driver'.
