device property: Add a function to obtain a node's prefix

2019-10-11T09:26:55Z

The prefix is used for printing purpose before a node, and it also works as a separator between two nodes. Signed-off-by: Sakari Ailus Acked-by: Rob Herring (for OF) Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

device property: Add fwnode_get_name for returning the name of a node

2019-10-11T09:26:55Z

The fwnode framework did not have means to obtain the name of a node. Add that now, in form of the fwnode_get_name() function and a corresponding get_name fwnode op. OF and ACPI support is included.

ACPI / property: fix handling of data_nodes in acpi_get_next_subnode()

2019-05-01T08:06:08Z

When the DSDT tables expose devices with subdevices and a set of hierarchical _DSD properties, the data returned by acpi_get_next_subnode() is incorrect, with the results suggesting a bad pointer assignment. The parser works fine with device_nodes or data_nodes, but not with a combination of the two. The problem is traced to an invalid pointer used when jumping from handling device_nodes to data nodes. The existing code looks for data nodes below the last subdevice found instead of the common root. Fix by forcing the acpi_device pointer to be derived from the same fwnode for the two types of subnodes. This same problem of handling device and data nodes was already fixed in a similar way by 'commit bf4703fdd166 ("ACPI / property: fix data node parsing in acpi_get_next_subnode()")' but broken later by 'commit 34055190b19 ("ACPI / property: Add fwnode_get_next_child_node()")', so this should probably go to linux-stable all the way to 4.12 Signed-off-by: Pierre-Louis Bossart Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J.
