dm: core: Add support for writing u32 with ofnode

2022-08-12T12:14:24+00:00

Add a new function to write an integer to an ofnode (live tree or
flat tree).

dm: core: Allow writing to a flat tree with ofnode

2022-08-12T12:14:24+00:00

In generally it is not permitted to implement an ofnode function only for
flat tree or live tree. Both must be supported. Also the code for
live tree access should be in of_access.c rather than ofnode.c which is
really just for holding the API-conversion code.

Update ofnode_write_prop() accordingly and fix the test so it can work
with flat tree too.

dm: core: Swap parameters of ofnode_write_prop()

2022-08-12T12:14:24+00:00

It is normal for the length to come after the value in libfdt. Follow this
same convention with ofnode.

dm: core: Introduce support for multiple trees

2022-08-12T12:14:23+00:00

At present ofnode only works with a single device tree, for the most part.
This is the control FDT used by U-Boot.

When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.

Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
start-up. Also, we don't need aliases to do fixups in the other FDT. So
make sure that flat tree and live tree processing are consistent in this
area.

dm: fix logic of lists_bind_fdt()

2022-07-26T08:30:56+00:00

If parameter drv of lists_bind_fdt() is specified, we shall bind only to
this very driver and to no other.

If the driver drv has an of_match property, we shall only bind to the
driver if it matches the compatible string of the device.

dm: avoid NULL dereference in lists_bind_fdt()

2022-07-26T08:30:56+00:00

If parameter drv of lists_bind_fdt() is specified, we want to bind to this
specific driver even if its field of_match is NULL.

If entry->of_match is NULL, we should not dereference it in a debug
statement.

dm: avoid NULL dereference in add_item()

acpi_add_other_item() passes dev = NULL. Instead of dev->name write the
string "other" to the debug log:
