From cb3862277b73b57ade3774b8fa684d3d7c324ba3 Mon Sep 17 00:00:00 2001 From: Dan Murphy Date: Mon, 2 May 2016 15:45:56 -0500 Subject: [PATCH] drivers: net: cpsw: Add reading of DT phy-handle node Add the ability to read the phy-handle node of the cpsw slave. Upon reading this handle the phy-id can be stored based on the reg node in the DT. The phy-handle also needs to be stored and passed to the phy to access any phy data that is available.
