of: Create function for counting number of phandles in a property

2013-02-13T10:09:31Z

This patch creates of_count_phandle_with_args(), a new function for counting the number of phandle+argument tuples in a given property. This is better than the existing method of parsing each phandle individually until parsing fails which is a horribly slow way to do the count. Tested on ARM using the selftest code. v3: - Rebased on top of selftest code cleanup patch v2: - fix bug where of_parse_phandle_with_args() could behave like _count_. - made of_gpio_named_count() into a static inline regardless of CONFIG_OF_GPIO Tested-by: Andreas Larsson Signed-off-by: Grant Likely Cc: Linus Walleij Cc: Rob Herring

OF: convert devtree lock from rw_lock to raw spinlock

2013-02-08T23:02:40Z

With the locking cleanup in place (from "OF: Fixup resursive locking code paths"), we can now do the conversion from the rw_lock to a raw spinlock as required for preempt-rt. The previous cleanup and this conversion were originally separate since they predated when mainline got raw spinlock (in commit c2f21ce2e31286a "locking: Implement new raw_spinlock"). So, at that point in time, the cleanup was considered plausible for mainline, but not this conversion. In any case, we've kept them separate as it makes for easier review and better bisection.

of: add 'const' to of_node_full_name parameter

2013-02-06T11:06:36Z

As the function just returns the np->full_name or the string "", the passed device_node pointer is not changed in any way. The passed parameter can therefore be a const pointer. Also, fix the following error from checkpatch.pl: ERROR: "foo* bar" should be "foo *bar" +static inline const char* of_node_full_name(const struct device_node *np) Signed-off-by: Steffen Trumtrar Signed-off-by: Grant Likely

of: *node argument to of_parse_phandle_with_args should be const

2012-12-11T17:30:16Z

The "struct device_node *" argument of of_parse_phandle_with_args() can be const. Making this change makes it explicit that the function will not modify a node.

of: add 'const' for of_parse_phandle parameter *np

2012-11-29T17:27:19Z

The existing function does not change the passed device_node pointer. It is only handed to of_get_property which itself takes a const struct device_node. of_parse_phandle() can therefore take a const pointer as well.

of: introduce for_each_matching_node_and_match()

2012-11-21T04:58:55Z

The following pattern of code is tempting: for_each_matching_node(np, table) { match = of_match_node(table, np); However, this results in iterating over table twice; the second time inside of_match_node(). The implementation of for_each_matching_node() already found the match, so this is redundant. Invent new function of_find_matching_node_and_match() and macro for_each_matching_node_and_match() to remove the double iteration, thus transforming the above code to: for_each_matching_node_and_match(np, table, &match) Signed-off-by: Stephen Warren Signed-off-by: Rob Herring
