From 829d51246fda25655b64224f2a19976797cf1897 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 6 Sep 2022 20:26:57 -0600 Subject: dm: core: Pass a root node to of_find_node_by_phandle() This function currently assumes that the control FDT is used. Update it to allow a root node to be passed, so it can work with any tree. Also add a comment to ofnode_get_by_phandle() so that its purpose is clear.
