Subject: [PATCH 01/18] arm/tegra: fix variable formatting in makefile

For some reason it started out using {} instead of (), and it's
proliferated from there. Switch back to ().

For now they are a minimal binding. It needs to be amended with
vendor-specific settings for phy setup and link tuning, etc.

v2: Added bindings specification and phy_type properties

+Tegra SOC USB controllers
+
+The device node for a USB controller that is part of a Tegra
+SOC is as described in the document "Open Firmware Recommended
+Practice : Universal Serial Bus" with the following modifications
+and additions :
+
+Required properties :
+ - compatible : Should be "nvidia,tegra20-ehci" for USB controllers
+   used in host mode.
+ - phy_type : Should be one of "ulpi" or "utmi".
+ - nvidia,vbus-gpio : If present, specifies a gpio that needs to be
+   activated for the bus to be powered.

Subject: [PATCH 03/18] USB: ehci-tegra: add probing through device tree

Rely on platform_data being passed through auxdata for now; more elaborate
bindings for phy config and tunings to be added.

v2: moved vbus-gpio check to the helper function, added check for !of_node,
    added usb2 clock to board-dt table.

Subject: [PATCH 09/18] arm/dt: tegra: Remove /memreserve/ from device-tree
 files

There are no drivers in the kernel at present which can make use of the
memory reserved by /memreserve/, so there is no point reserving it. Remove
/memreserve/ to allow the user more memory. It's also unclear whether any
future driver would actually require /memreserve/, or allocate memory
through some other mechanism.

Subject: [PATCH 10/18] arm/dt: tegra: Remove /chosen node

The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.

In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.

With board files, all I2C busses run at 400KHz. Fix the device-tree
to be consistent with this. It's possible this is incorrect, but at
least it keeps the board files and device-tree consistent.

Also, disable any I2C controllers that the board files don't register,
also for consistency.

Subject: [PATCH 12/18] arm/dt: tegra: Fix serial nodes to match board files

Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.

In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

Subject: [PATCH 13/18] arm/dt: tegra: Fix SDHCI nodes to match board files

Mark any SDHCI controllers that aren't registered by the board files as
disabled in the device-tree files.

In practice, these controllers:

* Have nothing hooked up to them at all, or
* For ports intended for SDIO usage, the drivers for anything that might
  be attached are not in the device-tree yet. If/when drivers appear, the
  SD/MMC port can be re-enabled.

The only possible exception is TrimSlice's mico SD slot, but that wasn't
enabled in the board files before anyway, and doesn't work when all the
SDHCI controllers are enabled anyway.

Subject: [PATCH 14/18] arm/tegra: convert tegra20 to GIC devicetree binding

Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
interrupt definitions in the dts files according to
Documentation/devicetree/bindings/arm/gic.txt

v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
  - Even with a dummy replacement if !CONFIG_OF, the reference from
    tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
  - It's plausible that tegra_dt_irq_match[] may need to contain more
    entries in the future, and defining what they are seems more suitable
    for board-dt.c than irq.c
v2 (swarren):
* Removed some stale GIC init code from board-dt.c
* Undid some accidental 0x -> 0x0 search/replace.

Subject: [PATCH 16/18] arm/dt: tegra: Use new compatible value for DVC I2C
 controller

Update the device tree to indicate which I2C controller is the DVC
controller. AUXDATA needs to be updated too, since the compatible
value changed.
