Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

those files can #include some other file e.g. for constant definitions.

This allows future use of #defines and header files in order to define
names for various constants, such as the IDs and flags in GPIO
specifiers. Use of those features will increase the readability of the
device tree files.

This branch contains the majority of the device tree changes for Tegra.
 Highlights include:
 
 * Many changes for Tegra114, and the Dalmore board, to enable pinctrl,
   SDHCI/MMC, PWM, DMA, I2C, KBC, SPI, battery, regulators.
 * Adding or enabling suspend wakeup sources on many boards, and adding
   suspend timing parameters, to support the system suspend patches.
 * 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.

Merge tag 'tegra-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/dt2

From Stephen Warren <swarren@wwwdotorg.org>:

ARM: tegra: device tree changes

This branch contains the majority of the device tree changes for Tegra.
Highlights include:

* Many changes for Tegra114, and the Dalmore board, to enable pinctrl,
  SDHCI/MMC, PWM, DMA, I2C, KBC, SPI, battery, regulators.
* Adding or enabling suspend wakeup sources on many boards, and adding
  suspend timing parameters, to support the system suspend patches.
* 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.

Andrew Chew b69cd984ef ARM: tegra: fix the status of PWM DT nodes
We should be defining the PWM nodes with status as "disabled" in the
chip-specific dtsi file, since we don't know whether specific boards
will use the PWM or not. This patch fixes the PWM node status for
Tegra20 and Tegra30.

Also fixed the one user of PWM, which is the Tegra20 medcom-wide board,
so that PWM is set to "okay" in the board-specific dts file.

The new clockframework introduced DT IDs for each clock. To be able to remove
the device registrations, this driver needs to be updated to use the DT IDs.
Note that the actual removal of the clk_register_clkdev() calls will be done

Stephen Warren 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.

While we're at it, remove the unit address from the cache-controller

The patch to add USB PHY nodes to device tree was written before Tegra

This will allow all clk_get_sys() calls in tegra_usb_phy.c to be replaced
by clk_get(phy->dev, clock_name), as part of converting the PHY driver to
a platform driver.

Stephen Warren 270f8ce312 ARM: tegra: define Tegra20 CAR binding
The Tegra20 CAR (Clock And Reset) Controller controls most aspects of
most clocks within Tegra20. The device tree binding models this as a
single monolithic clock provider, which exports many clocks. This reduces
the number of nodes needed in device tree to represent these clocks.

This binding is only useful for Tegra20; the set of clocks that exists on
Tegra30 is sufficiently different to merit its own binding.
