device property: Fix the length used in PROPERTY_ENTRY_STRING()

2019-03-23T13:35:24Z

commit 2b6e492467c78183bb629bb0a100ea3509b615a5 upstream. With string type property entries we need to use sizeof(const char *) instead of the number of characters as the length of the entry. If the string was shorter then sizeof(const char *), attempts to read it would have failed with -EOVERFLOW. The problem has been hidden because all build-in string properties have had a string longer then 8 characters until now.

device property: Define type of PROPERTY_ENRTY_*() macros

[ Upstream commit c505cbd45f6e9c539d57dd171d95ec7e5e9f9cd0 ] Some of the drivers may use the macro at runtime flow, like struct property_entry p[10]; ... p[index++] = PROPERTY_ENTRY_U8("u8 property", u8_data); In that case and absence of the data type compiler fails the build: drivers/char/ipmi/ipmi_dmi.c:79:29: error: Expected ; at end of statement drivers/char/ipmi/ipmi_dmi.c:79:29: error: got { Acked-by: Corey Minyard Cc: Corey Minyard Signed-off-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

device property: Introduce fwnode_property_get_reference_args

2017-07-21T22:04:51Z

The new fwnode_property_get_reference_args() interface amends the fwnode property API with the functionality of both of_parse_phandle_with_args() and __acpi_node_get_property_reference(). The semantics is slightly different: the cells property is ignored on ACPI as the number of arguments can be explicitly obtained from the firmware interface.

device property: Add fwnode_graph_get_port_parent

device property: Add support for fwnode endpoints

2017-03-28T22:00:29Z

Similar to OF endpoints, endpoint type nodes can be also supported on ACPI. In order to make it possible for drivers to ignore the matter, add a type for fwnode_endpoint and a function to parse them. On ACPI, find the child node index instead of relying on the "endpoint" property. Signed-off-by: Sakari Ailus Reviewed-by: Mika Westerberg Signed-off-by: Rafael J. Wysocki

device property: Make dev_fwnode() public

2017-03-28T22:00:28Z

The function to obtain a fwnode related to a struct device is useful for drivers that use the fwnode property API: it allows not being aware of the underlying firmware implementation. Signed-off-by: Sakari Ailus Reviewed-by: Mika Westerberg Signed-off-by: Rafael J. Wysocki
