of/irq: create interrupts-extended property

2013-10-28T23:48:14+00:00

The standard interrupts property in device tree can only handle
interrupts coming from a single interrupt parent. If a device is wired
to multiple interrupt controllers, then it needs to be attached to a
node with an interrupt-map property to demux the interrupt specifiers
which is confusing. It would be a lot easier if there was a form of the
interrupts property that allows for a separate interrupt phandle for
each interrupt specifier.

This patch does exactly that by creating a new interrupts-extended
property which reuses the phandle+arguments pattern used by GPIOs and
other core bindings.

interrupt parsing functions.

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

2013-02-13T10:09:31+00:00

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

of/selftest: Use selftest() macro throughout

2013-02-13T10:05:58+00:00

Some of the selftests are open-coded. Others use the selftest() macro
defined in drivers/of/selftest.c. The macro makes for cleaner selftest
code, so refactor the of_parse_phandle_with_args() tests to use it.

of/selftest: Fix GPIOs selftest to cover the 7th case

2013-02-13T10:05:57+00:00

The of_gpio_named_count() self test doesn't hit the out-of-range
condition even though it is coded. Fix the bug by increasing the for
loop range by one.

of: Add of_property_match_string() to find index into a string list

2012-01-28T17:29:20+00:00

Add a helper function for finding the index of a string in a string
list property.  This helper is useful for bindings that use a separate
*-name property for attaching names to tuples in another property such
as 'reg' or 'gpios'.

of: Add device tree selftests

2011-12-12T20:40:16+00:00

Add some runtime test cases for the library of device tree parsing functions.

v2: - Add testcase for phandle with 0 args
    - Don't run testcases if testcase data isn't present in device tree
