ee562dc34e ARM: tegra: pull Tegra210 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Brought in the correct Tegra210 CAR binding; the old file in U-Boot
  appears to be a renamed version of the Tegra124 bindings rather than
  the real Tegra210 version.
* Conversion of SPI and UART nodes to standard DMA bindings. U-Boot
  doesn't use DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot, including separation of the
  Tegra LIC (Legacy IRQ controller) and GIC.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* U-Boot has enabled PCIe for Tegra210, but the kernel hasn't yet.
* The GPIO node compatible value in the kernel explicitly includes
  Tegra124 values whereas U-Boot does not. I'll send a kernel patch to
  correct this.

The primary benefit of this change is that it adds all missing clocks and

Main changes:
* Conversion of SPI nodes to standard DMA bindings. U-Boot doesn't use

* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra114-mc.h since tegra114.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* USB node compatible values in U-Boot explicitly list Tegra114 values
  whereas the kernel does not. I'll send a kernel patch to correct this.

ce2f2d2ae7 ARM: tegra: pull Tegra30 SoC DT from Linux v4.7
The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Modification of PCIe memory region addresses. The HW memory layout is
  programmable, so this should work fine, and Beaver PCIe was tested
  without issue.
* Removal of pcie_xclk from the PCIe node and clock binding header. This
  clock doesn't exist and isn't used; only a reset with this ID exists.
* Conversion of SPI nodes to standard DMA bindings. U-Boot doesn't use
  DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Changed the phy_type value for the second USB port. This required board
  DTs to be updated to keep the same configuration.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra30-mc.h since tegra30.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* None.
