From c87b8fc569667610b4891cad1e4a663e5a94d8f8 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 1 Dec 2021 14:59:33 +0200 Subject: device property: Implement fwnode_graph_get_endpoint_count() Add fwnode_graph_get_endpoint_count() function to provide generic implementation of of_graph_get_endpoint_count(). The former by default only counts endpoints to available devices which is consistent with the rest of the fwnode graph API. By providing FWNODE_GRAPH_DEVICE_DISABLED flag, also unconnected endpoints and endpoints to disabled devices are counted.
