}; port@1 { (2) endpoint {...}; }; ... }; In above case, for_each_device_endpoint_of_node() loop 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 used from many venders can't know how many ports are used. Because the driver is very flexible/generic, it is impossible to know how many ports are used, 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. Then, Generic Sound Card want to handle each connection via "port" instead of "endpoint". But, it is very difficult to handle each "port" by for_each_device_endpoint_of_node(). Getting "port" by using of_get_parent() from "endpoint" doesn't work. see below. ports { port@0 { (1) endpoint@0 {...}; (2) endpoint@1 {...}; }; port@1 { (3) endpoint {...}; }; ... }; Add "port" base functions.

(X) node { (Y) ports { port@0 { endpoint { remote-endpoint = ...; };}; (A1) port@1 { endpoint { remote-endpoint = ...; }; (A2) endpoint { remote-endpoint = ...; };}; (B) port@2 { endpoint { remote-endpoint = ...; };}; }; }; For example, if I want to handle port@1's 2 endpoints (= A1, A2), I want to use like below A1 = of_graph_get_next_device_endpoint(port1, NULL); A2 = of_graph_get_next_device_endpoint(port1, A1); But 1st one will be error, because of_graph_get_next_device_endpoint() requested "parent" means "node" (X) or "ports" (Y), not "port". Below are OK /* These will be node/ports/port@0/endpoint */ of_graph_get_next_device_endpoint(node, NULL); of_graph_get_next_device_endpoint(ports, NULL); In other words, we can't handle A1/A2 directly via of_graph_get_next_device_endpoint() so far. There is another non intuitive behavior on of_graph_get_next_device_endpoint(). In case of if I could get A1 pointer for some way, and if I want to handle port@1 things, I would like use it like below /* * "ep" is now A1, and handle port1 things here, * but we don't know how many endpoints port1 has. * * Because "ep" is non NULL, we can use port1 * as of_graph_get_next_device_endpoint(port1, xxx) */ do { /* do something for port1 specific things here */ } while (ep = of_graph_get_next_device_endpoint(port1, ep)) But it also not worked as I expected. I expect it will be A1 -> A2 -> NULL, but it will be A1 -> A2 -> B, because of_graph_get_next_device_endpoint() will fetch endpoint beyond the port. It is not useful on generic driver like Generic Sound Card. It uses of_get_next_child() instead for now, but it is not intuitive, and not check node name (= "endpoint"). To handle endpoint more intuitive, create of_graph_get_next_endpoint() of_graph_get_next_endpoint(port1, NULL); // A1 of_graph_get_next_endpoint(port1, A1); // A2 of_graph_get_next_endpoint(port1, A2); // NULL Signed-off-by: Kuninori Morimoto --- drivers/of/property.c | 24 +++++++++++++++++++++++- include/linux/of_graph.h | 9 +++++++++ 2 files changed, 32 insertions(+), 1 deletion(-) diff --git a/drivers/of/property.c b/drivers/of/property.c index 083f92513f5e..ff37fd5194c1 100644 --- a/drivers/of/property.c +++ b/drivers/of/property.c @@ -669,6 +669,28 @@ struct device_node *of_graph_get_next_port(const struct device_node *parent, } EXPORT_SYMBOL(of_graph_get_next_port); +/** + * of_graph_get_next_endpoint() - get next endpoint node.
