Jonas Gorski	52b7f55cb3	brcm63xx: prevent usb clock state inconsistency on BCM6318 Return the same clock for usbh and usbd on BCM6318 to prevent the clock getting disabled despite being supposed to be enabled, e.g. by the following sequence: clk_enable(usbh); <- usbh->usage = 1, enabled clk_enable(usbd); <- usbd->usage = 1, enabled (no effect) clk_disable(usbd); <- usbd->usage = 0, -> disabled!

Florian Fainelli	0ecdc42f60	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.

brcm63xx: prevent usb clock state inconsistency on BCM6318

Return the same clock for usbh and usbd on BCM6318 to prevent the clock
getting disabled despite being supposed to be enabled, e.g. by the
following sequence:

	clk_enable(usbh); <- usbh->usage = 1, enabled
	clk_enable(usbd); <- usbd->usage = 1, enabled (no effect)
	clk_disable(usbd); <- usbd->usage = 0,  -> disabled!

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
