Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
but most of this is around legacy code and board support. We've found that
platform maintainers have a hard time separating all of these out and might
move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and clocksource
setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
- New backlight drivers for backlights used on Renesas shmobile platforms.
- Removal of Renesas leds driver.
- Shuffling of some of the new Broadcom platforms to give room for others in
the same mach directory. More in 2.13.

This patch adds mv643xx_eth and mvmdio device tree nodes for DT enabled
Kirkwood boards. Phy nodes are also added with reg property set on a
per-board basis.

When the pinmux mechanism was added in Kirkwood, the device driver
core was not yet providing the possibility of attaching pinmux
configurations to all devices, drivers had to do it explicitly, and
not all drivers were doing this.
Now that the driver core does that in a generic way, it makes sense to
attach the pinmux configuration to their corresponding devices.
This allows the pinctrl subsystem to show in debugfs to which device
is related which pins, for example:
pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41
pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42
pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43

In order to prepare the switch to the standard MMC device tree parser

When DT support for kirkwood was first introduced, there was no clock
infrastructure. As a result, we had to manually pass the
clock-frequency to the driver from the device node.
Unfortunately, on kirkwood, with minimal config or all module configs,
clock-frequency breaks booting because of_serial doesn't consume the
gate_clk when clock-frequency is defined.
The end result on kirkwood is that runit gets gated, and then the boot
fails when the kernel tries to write to the serial port.
Fix the issue by removing the clock-frequency parameter from all
kirkwood dts files.
Booted on dreamplug without earlyprintk and successfully logged in via
ttyS0.

Now that the mvsdio driver has a Device Tree binding, and the SDIO
controller is declared in kirkwood.dtsi, migrate the dreamplug board
to use the Device Tree to probe the SDIO controller and to mux this
interface properly.

Define both uarts in kirkwood.dtsi as they are common to all kirkwood
SoCs. Each board may enable all or none of them, so they are disabled
by default. uart0 is enabled for the dreamplug.
tclk can vary for each board, so we leave it undefined in the kirkwood
dtsi. Each board can then set it as appropriate when enabling the uart.

Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.
Then, switched to SPI based NOR flash.
After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support. First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.
Driver porting will start with the uart (see next patch), and progress
from there. Possibly, spi/flash/partitions will be next.
When done, board-dt.c will no longer be dreamplug specific, and dt's can
be made for the other kirkwood boards.
