of: add missing const for of_parse_phandle_with_args() in !CONFIG_OF

2016-06-03T12:27:55+00:00

commit 93c667ca2598bd84f1bd3f2fa176af69707699fe
("of: *node argument to of_parse_phandle_with_args should be const")
changed to const for struct device node *np,
but it cares CONFIG_OF case only, !CONFIG_OF case need it too.

Pull devicetree updates from Rob Herring:

- Rewrite of the unflattening code to avoid recursion and lessen the
stack usage.

- Rewrite of the phandle args parsing code to get rid of the fixed args
size. This is needed for IOMMU code.

- Sync to latest dtc which adds more dts style checking. These
warnings are enabled with "W=1" compiles.

- Tegra documentation updates related to the above warnings.

- A bunch of spelling and other doc fixes.

- Various vendor prefix additions.

device property: Avoid potential dereferences of invalid pointers

2016-04-27T21:40:02+00:00

Since fwnode may hold ERR_PTR(-ENODEV) or it may be NULL,
the fwnode type checks is_of_node(), is_acpi_node() and is
is_pset_node() need to consider it. Using IS_ERR_OR_NULL()
to check it.

of: Introduce of_phandle_iterator_args()

This helper function can be used to copy the arguments of a

of: Introduce of_for_each_phandle() helper macro

2016-04-19T22:25:14+00:00

With this macro any user can easily iterate over a list of
phandles. The patch also converts __of_parse_phandle_with_args()
to make use of the macro.

The of_count_phandle_with_args() function is not converted,
because the macro hides the return value of of_phandle_iterator_init(),
which is needed in there.

Move the code to walk over the phandles out of the loop in
