From 9277285f98f08522e646211e32adbdb6ae2469a1 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 20 Feb 2014 10:15:53 -0800 Subject: [PATCH] tty: serial: bcm63xx_uart: add support for DT probing Add a matching table for the the bcm63xx_uart driver on the compatible string "brcm,bcm6345-uart" which covers all BCM63xx implementations and reflects the fact that this block was first introduced with the BCM6345 SoC. Also make sure that we convert the id based on the uart aliases provided by the relevant Device Tree.
