fdt: Add a subnodes iterator macro

2014-10-22T22:56:41+00:00

The fdt_for_each_subnode() iterator macro provided by this patch can be
used to iterate over a device tree node's subnodes. At each iteration a
loop variable will be set to the next subnode.

fdt: Add functions to retrieve strings

2014-10-22T22:56:41+00:00

Given a device tree node, a property name and an index, the new function
fdt_get_string_index() will return in an output argument a pointer to
the index'th string in the property's value.

The fdt_get_string() is a shortcut for the above with the index being 0.

fdt: Add a function to get the index of a string

2014-10-22T22:56:40+00:00

Given a device tree node and a property name, the new fdt_find_string()
function will look up a given string in the string list contained in the
property's value and return its index.

fdt: Add a function to count strings

2014-10-22T22:56:40+00:00

Given a device tree node and a property name, the fdt_count_strings()
function counts the number of strings found in the property value.

fdt: Sync up with libfdt

2014-08-09T15:17:04+00:00

This brings in changes up to commit f9e91a48 in the libfdt repo.
Mostly this is whitespace/minor changes. But there are a few new
features:

- fdt_size_cells() and fdt_address_cells()
- fdt_resize()

libfdt: Add fdt_find_regions()

2013-06-26T14:18:56+00:00

Add a function to find regions in device tree given a list of nodes to
include and properties to exclude.

See the header file for full documentation.

libfdt: Add fdt_next_subnode() to permit easy subnode iteration

2013-05-14T19:37:25+00:00

Iterating through subnodes with libfdt is a little painful to write as we
need something like this:

for (depth = 0, count = 0,
	offset = fdt_next_node(fdt, parent_offset, &depth);
     (offset >= 0) && (depth > 0);
     offset = fdt_next_node(fdt, offset, &depth)) {
	if (depth == 1) {
		/* code body */
	}
}

Using fdt_next_subnode() we can instead write this, which is shorter and
easier to get right:

for (offset = fdt_first_subnode(fdt, parent_offset);
     offset >= 0;
     offset = fdt_next_subnode(fdt, offset)) {
	/* code body */
}

Also, it doesn't require two levels of indentation for the loop body.

Export fdt_stringlist_contains()

2013-05-10T23:04:49+00:00

This function is useful outside libfdt, so export it.
