From 3c8e42a7935f720c403612abf896d962a7aa1495 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 7 Jun 2017 11:08:20 +0200 Subject: [PATCH] dt-bindings: net: Add binding for the external clock for TI WiLink The external clock is provided to the TI WiLink combo chip and it's needed for any of the transport interfaces. However let's make it optional to avoid breaking existing platforms that yet doesn't specify the clock.
