dm: core: Make aliases_lookup static

2023-04-28T17:30:17Z

aliases_lookup is only referenced in of_access.c Signed-off-by: Bin Meng Reviewed-by: Simon Glass

dm: core: Expand integer-reading tests

2022-09-30T02:43:42Z

The current tests do not cover all the behaviour. Add some more. Tidy up a few inconsistencies between livetree and flattree which come to light with these tests. Also drop the -ENODATA error since it is never actually returned. Signed-off-by: Simon Glass

dm: core: Support writing a property to an empty node

2022-09-29T20:07:58Z

At present this does not work with livetree. Fix it and add a test. Signed-off-by: Simon Glass

dm: core: Allow adding ofnode subnodes

2022-09-29T20:07:58Z

Add this feature to the ofnode interface, supporting both livetree and flattree. If the node exists it is returned, along with a -EEXIST error. Update the functions it calls to handle this too. Signed-off-by: Simon Glass

dm: core: Pass a root node to of_find_node_by_phandle()

2022-09-29T20:07:58Z

This function currently assumes that the control FDT is used. Update it to allow a root node to be passed, so it can work with any tree. Also add a comment to ofnode_get_by_phandle() so that its purpose is clear. Signed-off-by: Simon Glass

dm: core: Add functions to read 8/16-bit integers

2022-09-14T19:23:03Z

Add functions to read 8/16-bit integers like the existing functions for 32/64-bit to simplify read of 8/16-bit integers from device tree properties. Signed-off-by: Stefan Herbrechtsmeier Reviewed-by: Marek Vasut Reviewed-by: Simon Glass Reviewed-by: Simon Glass

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

2022-08-12T12:14:24Z

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. Signed-off-by: Simon Glass

dm: core: Introduce support for multiple trees

2022-08-12T12:14:23Z

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. Signed-off-by: Simon Glass

doc: replace @return by Return:

2022-01-19T17:11:34Z

Sphinx expects Return: and not @return to indicate a return value. find . -name '*.c' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; find . -name '*.h' -exec \ sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \; Signed-off-by: Heinrich Schuchardt

dm: core: Fix up string-function documentation

2021-11-28T23:51:51Z

The details for of_property_read_string_helper() and ofnode_read_string_index() are a little inaccurate. Fix up the comments to avoid confusion. Signed-off-by: Simon Glass
