From 048c1df7e22b2d40c639837440527ba43b6a591c Mon Sep 17 00:00:00 2001 From: Kevin Cernekee Date: Tue, 21 Oct 2014 15:22:58 -0700 Subject: [PATCH] tty: serial: bcm63xx: Add support for unnamed clock outputs from DT The original non-DT bcm63xx clk code ignores the struct device argument and looks up a global clock name. DT platforms, by contrast, often just use a phandle to reference a clock node with no "clock-output-names" property. Modify the UART driver to support both schemes.
