device property: Introduce fwnode_call_bool_op() for ops that return bool

2017-07-12T11:32:46+00:00

fwnode_call_int_op() isn't suitable for calling ops that return bool
since it effectively causes the result returned to the user to be
true when an op hasn't been defined or the fwnode is NULL.

Address this by introducing fwnode_call_bool_op() for calling ops
that return bool.

device property: Move FW type specific functionality to FW specific files

2017-06-22T00:55:34+00:00

The device and fwnode property API supports Devicetree, ACPI and pset
properties. The implementation of this functionality for each firmware
type was embedded in the fwnode property core. Move it out to firmware
type specific locations, making it easier to maintain.

Depends-on: ("of: Move OF property and graph API from base.c to property.c")

device property: Read strings using string array reading functions

2017-03-29T20:59:40+00:00

Always read strings using of_property_read_string_array() instead of
of_property_read_string(). This allows using a single operation struct
callback for accessing strings.

Same for pset_prop_read_string_array() and pset_prop_read_string().

device property: fwnode_property_read_string_array() returns nr of strings

2017-03-28T22:00:30+00:00

Functionally fwnode_property_read_string_array() should match
of_property_read_string_array() and work as a drop-in substitute for the
latter. of_property_read_string_array() returns the number of strings read
if the target string pointer array is non-NULL. Make
fwnode_property_read_string_array() do the same.

device property: Fix reading pset strings using array access functions

2017-03-28T22:00:30+00:00

The length field value of non-array string properties is the length of the
string itself. Non-array string properties thus require specific handling.
Fix this.
