Subject: [PATCH] dt-bindings: net: Add binding for the external clock for TI
WiLink
Git-commit: 3c8e42a7935f720c403612abf896d962a7aa1495
Patch-mainline: v4.13
References: bsc#1085535
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.
