This patch set adds DT support for Marvell Dove SoC and three boards
equipped with this SoC. The work is based on device tree support for
Marvell Orion based SoCs introduced in 3.6-rc1.
The first three patches move mach-dove closer to Marvell Kirkwood's
setup code by unifying the clock setup routi
This patch adds clock gates from the clock gating control register
available on dove. All clock gates are hooked up to tclk, except for
gigabit ethernet controller (ge) which is a child of gephy to allow
both enabled/disabled at the same time.

This adds a generic DT_MACHINE for mach-dove. As with other orion based
SoCs there still is some glue code required to make all internal devices
work, i.e. auxdata is provided to pass clocks to corresponding device
drivers.

This patch synchronizes the clock setup of dove with other orion-based
platforms.
In dove_find_tclk there was a note about DOVE_SAMPLE_HI/LO register to
detect tclk. While it might be possible to set a different tclk frequency
with reset strapping the Dove datasheets don't tell anything about tclk
Added file /sys/devices/.../tty/ttySX/uartclk to allow read/modify
uartclk value in struct uart_port in serial_core via sysfs.
It simplifies initialization of no-name cards that have non-standard
oscillator speed while having no distinguishing PCI IDs to allow
autodetection.

Sorry for taking such a long time to re-review this.

Technically, no, nothing is overwritten
Several improvements in error handling:
- do not report success if alloc_chrdev_region() failed
- check for error code of cdev_add()
- use unregister_chrdev_region() instead of unregister_chrdev()
if class_create() failed

Changes since v1:
- Added support for external gpio and wakeup interrupts for Exynos4.
This patch series adds a common pinctrl driver for all Samsung platforms and
enables the pinctrl driver support for Exynos4210 based device tree enabled
platforms. The scope of this driver is limited to only dev
Add a new device tree enabled pinctrl and gpiolib driver for Samsung
SoC's. This driver provides a common and extensible framework for all
Samsung SoC's to interface with the pinctrl and gpiolib subsystems. This
driver supports only device tree based instantiation and hence can be
used only on thos
Pinctrl driver, when enabled, registers all the gpio pins and hence the
registration of gpio pins by this driver can be skipped.

Pinctrl driver includes support for configuring the external wakeup
interrupts. On exynos platforms that use pinctrl driver, the setup
of wakeup interrupts in the exynos platform code can be skipped.

Add information about the Exynos4210 pin banks and driver data which is
used by the Samsung pinctrl driver. In addition to this, the support for
external gpio and wakeup interrupt support is included and hooked up with
the Samsung pinctrl driver.

I'm experiencing a stall with Ceph daemons communicating over TCP that
occurs reliably with 3.6-rc1 (and linus/master) but not 3.5. The basic
situation is:
- the socket is two processes communicating over TCP on the same host, e.g.
tcp0 2164849 10.214.132.38:6801 10.214.132.38:5
