Grant Likely 40aad3c1a9 dt/bindings: Remove all references to device_type "ethernet-phy"
The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the
.dts files.

This patch was generated mechanically with the following command and
then verified by looking at the diff.

sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'`

Jason Cooper dcdf14c729 ARM: mvebu: dts: remove unneeded linux,default-state from led nodes
Generally, power LEDs should indicate when power is applied, and go out
once power is removed.  _Not_ annoy the developer with migraine-inducing
blinking reminicent of some badly animated television series designed to
sell sugar to children.

On a more serious note, most of these OS-specific properties aren't
necessary and should be removed.  I left two that are legitimately tying
disk LEDs to disk activity.  Other than that, we keep the state the
bootloader left them in until userspace changes the state via sysfs.

Linus Torvalds 44598f98b9 ARM: SoC board updates for 3.12
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.

Thomas Petazzoni 4d05871a78 arm: kirkwood: iomega ix2-200: move pinmux configs to the right devices
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.

Note that some of the LEDs pinmux configurations are kept in the
pinctrl node, because they are not used by the gpio-leds driver.

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

Jason Cooper 93fff4ce19 ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency
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.
