ceff2676b0 SERIAL: MIPS: lantiq: implement OF support
Add devicetree and handling for our new clkdev clocks. The patch is rather
straightforward. .of_match_table is set and the 3 irqs are now loaded from the
devicetree.

This series converts the lantiq target to clkdev amongst other things. The
driver needs to handle two clocks now. The fpi bus clock used to derive the
divider and the clock gate needed on some socs to make the secondary port work.

Fix up Conflicts in:
 - drivers/tty/serial/8250_pci.c
	Trivial conflict with removed duplicate device ID
 - drivers/tty/serial/atmel_serial.c
	Annoying silly conflict between "specify the port num via
	platform_data" and other changes to atmel_console_init

9cfb5c05fe TTY: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.
