of: unittest: Fix of_count_phandle_with_args() expected value message

2024-01-25T23:45:09+00:00

[ Upstream commit 716089b417cf98d01f0dc1b39f9c47e1d7b4c965 ]

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

2024-01-25T23:45:08+00:00

[ Upstream commit 4dde83569832f9377362e50f7748463340c5db6b ]

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.

The documented numeric return values do not match the actual returned

of: address: Consolidate bus .map() functions

2023-10-27T21:37:42+00:00

The bus .map() functions vary only by checking the flag cells values
and skipping over any flag cells to read the addresses. Otherwise they
all do the same reading 'ranges' address and size and returning the
address's offset if it is within the 'ranges' entry.

Refactor all the .map() functions to pass in the flag cell size so that
each bus can check the bus specific flags and then call a common
function to do everything else.

of: address: Store number of bus flag cells rather than bool

2023-10-27T21:37:42+00:00

It is more useful to know how many flags cells a bus has rather than
whether a bus has flags or not as ultimately the number of cells is the
information used. Replace 'has_flags' boolean with 'flag_cells' count.
