Stephen Warren 553c0a200e ARM: tegra: set up /aliases entries for RTCs
This ensures that the PMIC RTC provides the system time, rather than
the on-SoC RTC, which is not battery-backed.

tegra124-venice2.dts isn't touched yet since we haven't added any off-
SoC RTC device to its device tree.

Use key code macros for all key code refernced for keys.

For tegra20-seaboard.dts and tegra20-harmony.dts:
  The key comment for key (16th row and 1st column) is KEY_KPSLASH but
  code is 0x004e which is the key code for KEY_KPPLUS. As there other
  key exist with KY_KPPLUS, I am assuming key code is wrong and comment
  is fine. With this assumption, I am keeping the key code as KEY_KPSLASH.

Stephen Warren 578990537a ARM: tegra: fix node sort order
For Tegra DT files, I've been attempting to keep the nodes sorted in
the order:
1) Nodes with reg, in order of reg.
2) Nodes without reg, alphabetically.

This patch fixes a few escapees that I missed:-(

The diffs look larger than they really are, because sometimes when one
node was moved up or down, diff chose to represent this as many other
nodes being moved the other way!

Stephen Warren 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.

Stephen Warren 30ca2226be ARM: tegra: always enable USB VBUS regulators
This fixes a regression exposed during the merge window by commit
9f310de "ARM: tegra: fix VBUS regulator GPIO polarity in DT"; namely that
USB VBUS doesn't get turned on, so USB devices are not detected. This
affects the internal USB port on TrimSlice (i.e. the USB->SATA bridge, to
which the SSD is connected) and the external port(s) on Seaboard/
Springbank and Whistler.

The Tegra DT as written in v3.11 allows two paths to enable USB VBUS:

1) Via the legacy DT binding for the USB controller; it can directly
   acquire a VBUS GPIO and activate it.

2) Via a regulator for VBUS, which is referenced by the new DT binding
   for the USB controller.

Those two methods both use the same GPIO, and hence whichever of the
USB controller and regulator gets probed first ends up owning the GPIO.
In practice, the USB driver only supports path (1) above, since the
patches to support the new USB binding are not present until v3.12:-(

In practice, the regulator ends up being probed first and owning the
GPIO. Since nothing enables the regulator (the USB driver code is not
yet present), the regulator ends up being turned off. This originally
caused no problem, because the polarity in the regulator definition was
incorrect, so attempting to turn off the regulator actually turned it
on, and everything worked:-(

However, when testing the new USB driver code in v3.12, I noticed the
incorrect polarity and fixed it in commit 9f310de "ARM: tegra: fix VBUS
regulator GPIO polarity in DT". In the context of v3.11, this patch then
caused the USB VBUS to actually turn off, which broke USB ports with VBUS
control. I got this patch included in v3.11-rc1 since it fixed a bug in
device tree (incorrect polarity specification), and hence was suitable to
be included early in the rc series. I evidently did not test the patch at
all, or correctly, in the context of v3.11, and hence did not notice the
issue that I have explained above:-(

Fix this by making the USB VBUS regulators always enabled. This way, if
the regulator owns the GPIO, it will always be turned on, even if there
is no USB driver code to request the regulator be turned on. Even
ignoring this bug, this is a reasonable way to configure the HW anyway.

If this patch is applied to v3.11, it will cause a couple pretty trivial
conflicts in tegra20-{trimslice,seaboard}.dts when creating v3.12, since
the context right above the added lines changed in patches destined for
v3.12.

This allows future use of #defines and header files in order to define

specifiers. Use of those features will increase the readability of the
device tree files.

Linus Torvalds db5b0ae007 ARM: arm-soc: device tree conversions and enablement
Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
 smaller series as well.
 
 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.

Stephen Warren 6529e63805 ARM: dt: tegra: seaboard: add regulators
Seaboard uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.

Two data sources were used for the data encoded here:
* The HW defaults, as extracted from real HW.
* The schematic, which specifies a voltage for each LDO rail.

In most cases these sources matched. The only differences is:

ldo6: The HW default on Springbank is 2.85v. The HW default on Seaboard
is 1.8v. The schematics for both Springbank and Seaboard match at 2.85v.
However, internal research indicates that the schematics are incorrectly
labelled, and 1.8v is correct. The ChromeOS kernel also uses 1.8v.

Note that these settings don't entirely match those in the ChromeOS
kernel found at the URL below. However, the selected values generally
cause no behavior change in the kernel, and so were picked to avoid
regressions.

Stephen Warren 702b0e4f2f ARM: dt: tegra: rename board files to match SoC
Most ARM ${board}.dts files are already named ${soc}-${board}.dts. This
change modifies the Tegra board files to be named the same way for
consistency.

Once a related change is made in U-Boot, this will cause both U-Boot and
the kernel to use the same names for the .dts files and SoC identifiers,
thus allowing U-Boot's recently added "soc" and "board" environment
variables to be used to construct the name of Tegra .dtb files, and hence
allow board-generic U-Boot bootcmd scripts to be written.
