The driver explicitly requests a clock rate for the UART, but it is
off by a factor of four from the dividers that it programs into the
UART. Fix this by setting the rate to 1/4 of the current value.

* 'next/dt' of git://git.linaro.org/people/arnd/arm-soc:
ARM: gic: use module.h instead of export.h
ARM: gic: fix irq_alloc_descs handling for sparse irq
ARM: gic: add OF based initialization
ARM: gic: add irq_domain support
irq: support domains with non-zero hwirq base
of/irq: introduce of_irq_init
ARM: at91: add at91sam9g20 and Calao USB A9G20 DT support
ARM: at91: dt: at91sam9g45 family and board device tree files
arm/mx5: add device tree support for imx51 babbage
arm/mx5: add device tree support for imx53 boards
ARM: msm: Add devicetree support for msm8660-surf
msm_serial: Add devicetree support
msm_serial: Use relative resources for iomem
Fix up conflicts in arch/arm/mach-at91/{at91sam9260.c,at91sam9g45.c}
Add devicetree support to the msm_serial driver. Clocks are still
queried by direct name from the driver until device tree clock support
is implemented.

Device tree iomem resources are only accessible by index, and not by
name. The msm_serial devices always have either 1 or 2 iomem
resources, that are always in the same order. Convert the
platform_get_resource_byname into just platform_get_resource to
facilitate device tree conversion.

It doesn't make sense to set console to uart_port in console->setup.
At that time the console is set by uart_add_one_port already.
The call chain looked like:
uart_add_one_port()
uport->cons = drv->cons; <= once
uart_configure_port()
register_console()
console->setup()
port->cons = co; <= second time

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
