From 0ecdc42f60397cd015ba8cb57f6835eb59950e45 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 14 Jan 2014 05:23:39 +0000 Subject: [PATCH] brcm63xx: improve BCM6318 support Provide clock toggling for the USB host and slave controller as well as for the Ethernet Switch. The bcm63xx_enetsw driver is changed not to use request_mem_region() as the Roboswitch register overlaps with the Roboswitch IUDMA channels, hence making the driver return -EBUSY. A future fix might be to use variable size RSET_ENETSW sizes depending on the chip we are targetting.
