    of: Create function for counting number of phandles in a property · bd69f73f
    Grant Likely authored
    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
