We need to get ofnode from a phandle, add interface to support
both live dt and fdt.

core: ofnode: add ofnode_get_parent function

2018-02-23T19:47:47+00:00

The Rockchip video drivers need to walk the ofnode-parrents to find
an enclosing device that has a UCLASS_DISPLAY driver bound.  This
adds a ofnode_get_parent()-function that returns the parent-node.

dm: core: Add ofnode_for_each_subnode()

Add a convenience macro to iterate over subnodes of a node. Make use of
this where appropriate in the code.

ofnode: add {ofnode, dev}_read_resource_byname()

2017-08-29T14:56:17+00:00

Linux supports platform_get_resource_byname() to look up a resource
by name.

We want a similar helper.  It is useful when a device node has named
register regions.

dm: core: add ofnode_count_phandle_with_args()

2017-07-28T21:34:08+00:00

This function is usefull to get phandle number contained
in a property list.
For example,  this allows to allocate the right amount
of memory to keep clock's reference contained into the
"clocks" property.

To implement it, either of_count_phandle_with_args() or
fdtdec_parse_phandle_with_args() are used respectively
for live tree and flat tree.
By passing index = -1, these 2 functions returns the
number of phandle contained into the property list.

Add also the dev_count_phandle_with_args() based on
ofnode_count_phandle_with_args()

dm: core: Add ofnode_read_resource()

2017-07-28T18:02:47+00:00

We sometimes need to read a resource from an arbitrary node. In any case
for consistency we should not put the live-tree switching code in
a dev_read_...() function. Update this to suit.

dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()

2017-07-11T16:08:20+00:00

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.
