fd6441ec0f ARM: tegra: modify Tegra30 USB2 default phy_type to UTMI
Modify Tegra30 default USB2 phy_type to UTMI; this matches
power-on-reset defaults and is expected to be the common case.

The current implementation is likely an incorrect
carry-over from Tegra20, where USB2 does default to ULPI.

58ecb23f64 ARM: tegra: add missing unit addresses to DT
DT node names should include a unit address iff the node has a reg
property. For Tegra DTs at least, we were previously applying a different
rule, namely that node names only needed to include a unit address if it
was required to make the node name unique. Consequently, many unit
addresses are missing. Add them.

d8f64797c5 ARM: tegra: add missing clock documentation to DT bindings
Many of the Tegra DT binding documents say nothing about the clocks or

This patch simply updates the documentation file to match the implicit

 * Adding or enabling suspend wakeup sources on many boards, and adding

 * Adding clocks to the audio-related nodes, so that in 3.11, the audio
   driver can pull these clocks from device tree rather than hard-coding
   clock names.
 * Some small DT fixes/cleanup.
 
 This branch is based on the previous clk pull request.

8364f5d965 ARM: tegra: remove clock-frequency properties from serial nodes
Currently, the serial nodes define both a clock-frequency and a clocks
property. We should not provide both, since they might conflict.

In practice, this also causes problems since the of_serial driver uses
the clock-frequency property in preference to the clocks property, and
hence doesn't clk_prepare_enable() the clock, which may then leave it
with no known users, and hence the common clock framework will disable
it, thus breaking the port, which is usually the console.

73368ba0e1 ARM: tegra: add TWD to device tree
This will allow timer.c to use twd_local_timer_of_register(), and
hence not need to hard-code the TWD address or IRQ.

380e04ac2c ARM: tegra: define DT bindings for and instantiate RTC
The Tegra RTC maintains seconds and milliseconds counters, and five alarm
registers. The alarms and other interrupts may wake the system from
low-power state.

Define a DT binding for this HW module, and add the module into the Tegra
device tree files.

2f2b7fb202 ARM: tegra: define DT bindings for and instantiate timer
The Tegra timer provides a number of 29-bit timer channels, a single
32-bit free running counter, and in the Tegra30 variant, 5 watchdog modules.
The first two channels may also trigger a legacy watchdog reset.

Define a DT binding for this HW module, and add the module into the Tegra
device tree files.

PWM devices can be referenced in the DT by phandle and per-chip index.
In order for this to work properly, the PWM controller needs to have a

Linus Torvalds
9ec97169e7 Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwm
Pull PWM subsystem from Thierry Reding:
 "The new PWM subsystem aims at collecting all implementations of the
  legacy PWM API and to eventually replace it completely.

  The subsystem has been in development for over half a year now and
  many drivers have already been converted.  It has been in linux-next
  for a couple of weeks and there have been no major issues so I think
  it is ready for inclusion in your tree."

Arnd Bergmann <arnd@arndb.de>:
 "Very much Ack on the new subsystem.  It uses the interface
  declarations as the previously separate pwm drivers, so nothing
  changes for now in the drivers using it, although it enables us to
  change those more easily in the future if we want to.

  This work is also one of the missing pieces that are required to
  eventually build ARM kernels for multiple platforms, which is
  currently prohibited (amongs other things) by the fact that you cannot
  have more than one driver exporting the pwm functions."
