device property: Export fwnode_get_name()

2020-03-16T06:47:58+00:00

This makes it possible to take advantage of the function in the device drivers. Signed-off-by: Heikki Krogerus Acked-by: Rafael J. Wysocki Link: https://lore.kernel.org/r/20200302135353.56659-8-heikki.krogerus@linux.intel.com Signed-off-by: Greg Kroah-Hartman

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

2019-10-11T09:26:55+00:00

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

2019-10-11T09:26:55+00:00

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.

device property: Add functions for accessing node's parents

2019-10-11T09:26:55+00:00

Add two convenience functions for accessing node's parents: fwnode_count_parents() returns the number of parent nodes a given node has. fwnode_get_nth_parent() returns node's parent at a given distance from the node itself.

device property: Move fwnode_get_parent() up

2019-10-11T09:26:55+00:00

Move fwnode_get_parent() above fwnode_get_next_parent(), making the order the same as in the header file. Signed-off-by: Sakari Ailus Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

device property: Introduce fwnode_find_reference()

2019-06-03T08:55:38+00:00

In most cases the references that the drivers look for don't have any arguments. This introduces a wrapper function for fwnode_property_get_reference_args() that looks for references by using only the name and index.

device property: Add fwnode_graph_get_endpoint_by_id()

2019-04-18T14:44:05+00:00

fwnode_graph_get_endpoint_by_id() is intended for obtaining local endpoints by a given local port. fwnode_graph_get_endpoint_by_id() is slightly different from its OF counterpart, of_graph_get_endpoint_by_regs(): instead of using -1 as a value to indicate that a port or an endpoint number does not matter, it uses flags to look for equal or greater endpoint. The port number is always fixed. It also returns only remote endpoints that belong to an available device, a behaviour that can be turned off with a flag.

device property: fix fwnode_graph_get_next_endpoint() documentation

device property: Remove struct property_set

2018-11-26T17:19:11+00:00

Replacing struct property_set with the software nodes that were just introduced. The API and functionality for adding properties to devices remains the same, however, the goal is to convert the drivers to use the API for software nodes when the device has no real firmware node, and use the old API only when "extra" build-in properties are needed.
