+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.

+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.
