of_graph_get_endpoint_by_regs — get endpoint node of specific identifiers
struct device_node * of_graph_get_endpoint_by_regs ( | const struct device_node * parent, |
int port_reg, | |
int reg) ; |
parent
Pointer to parent node
port_reg
Identifier (value of reg property) of the parent port node
reg
Identifier (value of reg property) of the endpoint node
Find an 'endpoint' node pointer which is identified by reg and is the child of a port node identified by port_reg. reg and port_reg are ignored when they are -1.
See of_graph_get_next_endpoint
for more information about the expected
form of the parent node and the parent port node.
