Subject: [PATCH] ARM: BCM5301X: Enable UART on Netgear R8000
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It was tested by LEDE users, all we need is to adjust clock frequency.
While we're at it create a separated DTS include file to share code with
other BCM4709 devices easier.
