}; port@1 { (2) endpoint {...}; }; ... }; In above case, it finds endpoint as (1) -> (2) -> ... Basically, user/driver knows which port is used for what, but not in all cases. For example on flexible/generic driver case, how many ports are used is not fixed. For example Sound Generic Card driver which is very flexible/generic and used from many venders can't know how many ports are used, and used for what, because it depends on each vender SoC and/or its used board. And more, the port can have multi endpoints. For example Generic Sound Card case, it supports many type of connection between CPU / Codec, and some of them uses multi endpoint in one port. see below. ports { (A) port@0 { (1) endpoint@0 {...}; (2) endpoint@1 {...}; }; (B) port@1 { (3) endpoint {...}; }; ... }; Generic Sound Card want to handle each connection via "port" base instead of "endpoint" base. But, it is very difficult to handle each "port" via existing for_each_endpoint_of_node(). Because getting each "port" via of_get_parent() from each "endpoint" doesn't work. For example in above case, both (1) (2) endpoint has same "port" (= A). Add "port" base functions.

(X) node { (Y) ports { (P0) port@0 { endpoint { remote-endpoint = ...; };}; (P10) port@1 { endpoint { remote-endpoint = ...; }; (P11) endpoint { remote-endpoint = ...; };}; (P2) port@2 { endpoint { remote-endpoint = ...; };}; }; }; For example, if I want to handle port@1's 2 endpoints (= P10, P11), I want to use like below P10 = of_graph_get_next_endpoint(port1, NULL); P11 = of_graph_get_next_endpoint(port1, P10); But 1st one will be error, because of_graph_get_next_endpoint() requested 1st parameter is "node" (X) or "ports" (Y), not but "port". Below works well, but it will get P0 P0 = of_graph_get_next_endpoint(node, NULL); P0 = of_graph_get_next_endpoint(ports, NULL); In other words, we can't handle P10/P11 directly via of_graph_get_next_endpoint(). There is another non intuitive behavior on of_graph_get_next_endpoint(). In case of if I could get P10 pointer for some way, and if I want to handle port@1 things by loop, I would like use it like below /* * "ep" is now P10, and handle port1 things here, * but we don't know how many endpoints port1 have. * * Because "ep" is non NULL now, we can use port1 * as of_graph_get_next_endpoint(port1, xxx) */ do { /* do something for port1 specific things here */ } while (ep = of_graph_get_next_endpoint(port1, ep)) But it also not worked as I expected. I expect it will be P10 -> P11 -> NULL, but it will be P10 -> P11 -> P2, because of_graph_get_next_endpoint() will fetch "endpoint" beyond the "port". It is not useful for generic driver. To handle endpoint more intuitive, create of_graph_get_next_port_endpoint() of_graph_get_next_port_endpoint(port1, NULL); // P10 of_graph_get_next_port_endpoint(port1, P10); // P11 of_graph_get_next_port_endpoint(port1, P11); // NULL Signed-off-by: Kuninori Morimoto --- drivers/of/property.c | 27 +++++++++++++++++++++++++++ include/linux/of_graph.h | 21 +++++++++++++++++++++ 2 files changed, 48 insertions(+) diff --git a/drivers/of/property.c b/drivers/of/property.c index 6a5d27dd0c64..bf15bed69e6a 100644 --- a/drivers/of/property.c +++ b/drivers/of/property.c @@ -667,6 +667,33 @@ struct device_node *of_graph_get_next_port(const struct device_node *parent, } EXPORT_SYMBOL(of_graph_get_next_port); +/** + * of_graph_get_next_port_endpoint() - get next endpoint node in port. + * If it reached to end of the port, it will return NULL. + * @port: pointer to the target port node + * @prev: previous endpoint node, or NULL to get first + * + * Return: An 'endpoint' node pointer with refcount incremented.
