Subject: [PATCH V2 1/8] MIPS: BCM63XX: add clkdev lookup support
Enable clkdev lookup support to allow us providing clocks under
different names to devices more easily, so we don't need to care
about clock name clashes anymore.

Codify using a named clock for the refclk of the uart. This makes it

From b98027285bd1fa95da0645a4234a5fc1f1a83f92 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jonas.gorski@gmail.com>
Date: Sun, 26 Feb 2017 11:59:52 +0100
Subject: [PATCH V2 8/8] MIPS: BCM63XX: split out swpkt_sar/usb clocks
Make the secondary switch clocks their own clocks. This allows proper
enable reference counting between SAR/XTM and the main switch clocks,
and controlling them individually from drivers.
