of_count_phandle_with_args — find the number of phandles in a property
int of_count_phandle_with_args ( | const struct device_node * np, |
const char * list_name, | |
const char * cells_name) ; |
np
Pointer to node that contains the phandle list
list_name
Name of property in node np that contains the phandle list
cells_name
Name of property in target node that contains phandle's argument count
It is a typical pattern to encode a list of phandle and variable arguments into a single property. The number of arguments is encoded by a property in the phandle-target node. For example, a gpios property would contain a list of GPIO specifiers consisting of a phandle and 1 or more arguments. The number of arguments are determined by the #gpio-cells property in the node pointed to by the phandle.
