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.

Laxman Dewangan 6bccbd5e18 ARM: tegra: convert device tree files to use key defines
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 1bd0bd499d ARM: tegra: use #include for all device trees
Replace /include/ (dtc) with #include (C pre-processor) for all Tegra DT
files, so that gcc -E handles the entire include tree, and hence any of
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.

Laxman Dewangan 3cc404de24 ARM: dt: tegra: harmony: add regulators
Harmony uses a TPS6586x regulator. Instantiate this, and hook up a
couple of fixed GPIO-controlled regulators too.

Based on Ventana regulator patch by Stephen Warren <swarren@nvidia.com>
and converted to Harmony.

swarren made the following changes:
* Added ldo0 regulator configuration to device tree, and updated
  board-harmony-pcie.c for the new regulator name.
* Fixed vdd_1v05's voltage from 10.5V to 1.05V.
* Modified board-harmony-pcie.c to obtain the en_vdd_1v05 GPIO number at
  run-time from device tree instead of hard-coding it.
* Removed board-harmony{-power.c,.h} now that they're unused.
* Disabled vdd_1v05 regulator; the code in board-harmony-pcie.c hijacks
  this GPIO for now. This will be fixed when the PCIe driver is re-
  written as a driver. The code can't regulator_get("vdd_1v05") right
  now, because the vdd_1v05 regulator's probe gets deferred due to its
  supply being the PMIC, which gets probed after the regulator the first
  time around, and this dependency is only resolved by repeated probing,
  which happens when deferred_probe_initcall() is called, which happens
  in a late initcall, whose runtime order relative to harmony_pcie_init()
  is undefined, since that's also called from a late initcall.
* Removed unused harmony_pcie_initcall().

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.
