OF: Add of_match_ptr() macro

2012-06-04T21:21:30+00:00

Add a macro of_match_ptr() that allows the .of_match_table
entry in the driver structures to be assigned without having
an #ifdef xxx NULL for the case that OF is not enabled

dt: add empty of_get_property for non-dt

2011-08-09T17:27:16+00:00

The patch adds empty function of_get_property for non-dt build, so that
drivers migrating to dt can save some '#ifdef CONFIG_OF'.

This also fixes the current Tegra compile problem in linux-next.

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 of_alias_scan and of_alias_get_id

2011-08-03T12:02:31+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.

of: constify property name parameters for helper functions

2011-08-02T15:50:47+00:00

The helper functions for reading u32 integers, u32 arrays and strings
should have the property name as a const pointer.

dt: add empty of_property_read_u32[_array] for non-dt

2011-07-08T18:52:33+00:00

The patch adds empty functions of_property_read_u32 and
of_property_read_u32_array for non-dt build, so that drivers
migrating to dt can save some '#ifdef CONFIG_OF'.

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.

dt: add 'const' for of_property_read_string parameter **out_string

2011-07-04T05:47:22+00:00

The existing dt codes usually call of_get_property to get a string
property and save it as a 'const char *'.  The patch adds'const' for
of_property_read_string parameter **out_string to make the converting
of existing code a little easier.

dt: add helper functions to read u32 and string property values

2011-06-30T19:02:10+00:00

Add helper functions to retrieve unsigned integer and string property
values from properties of a device node. These helper functions can be
used to lookup a property in a device node, perform error checking and
read the property value.
