of: Add of_property_match_string() to find index into a string list

2015-08-06T23:32:16+00:00

commit 7aff0fe33033fc75b61446ba29d38b1b1354af9f upstream.

Add a helper function for finding the index of a string in a string
list property.  This helper is useful for bindings that use a separate
*-name property for attaching names to tuples in another property such
as 'reg' or 'gpios'.

of: Fix missing memory initialization on FDT unflattening

2013-10-26T20:06:00+00:00

commit 0640332e073be9207f0784df43595c0c39716e42 upstream.

Any calls to dt_alloc() need to be zeroed. This is a temporary fix, but
the allocation function itself needs to zero memory before returning
it. This is a follow up to patch 9e4012752, "of: fdt: fix memory
initialization for expanded DT" which fixed one call site but missed
another.

dt: add helper to read 64-bit integers

2011-10-04T22:59:53+00:00

Add a helper similar to of_property_read_u32() that handles 64-bit
integers.

v2/v3: constify device node and property name parameters.

dt: add of_alias_scan and of_alias_get_id

2011-09-22T17:12:10+00:00

The patch adds function of_alias_scan to populate a global lookup
table with the properties of 'aliases' node and function
of_alias_get_id for drivers to find alias id from the lookup table.

v3: Split out automatic addition of aliases on id lookup so that it can be
    debated separately from the core functionality.
v2: - Add of_chosen/of_aliases populating and of_alias_scan() invocation
    for OF_PROMTREE.
    - Add locking
    - rework parse loop

Revert "dt: add of_alias_scan and of_alias_get_id"

2011-08-04T10:26:24+00:00

This reverts commit 750f463a749e28464151ad26938d11b07b1c43cb.

of_alias_* still needs work to be generalized for 'promtree' dt
platforms, and to no implicitly create entries for available ids.

dt: add helper function to read u32 arrays

2011-07-06T20:58:09+00:00

Rework of_property_read_u32 to read an array of values. Then
of_property_read_u32 becomes an inline with array size of 1.

Also make struct device_node ptr const.
