f53dcc0e35 tegra: fdt: Ensure that the console UART is enabled
Many tegra boards have the console UART node disabled. With livetree this
prevents serial from working since it does not 'force' the console to be
bound. Updates the affected boards to fix this error.

The boards were checked with:

for b in $(grep  tegra boards.cfg  |grep -v integrator | \
		awk '{print $7}' | sort); do
	echo $b;
	fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay;
done

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.

67748a73b1 mmc: tegra: use correct alias for SDHCI/MMC nodes
The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

29ce99955e apalis/colibri_t30: fix usb dm regression
Unfortunately currently both Apalis T30 as well as Colibri T30 crash
upon starting USB host support. This is due to the following patch not
having taken into account that our T30 device trees were defaulting to
peripheral only mode instead of otg:

commit ddb9a502d1
dm: usb: tegra: Move most of init/uninit into a function

This patch fixes this by defaulting to otg now.

72731118e2 apalis/colibri_t30: fix MMC/SD card detect GPIOs
This fixes the MMC/SD card detect GPIOs for Apalis T30 which got broken
by the following commit:

2b2b50bc87 "dm: tegra: dts: Use TEGRA_GPIO() macro for all GPIOs"

While at it also re-add the comments describing which particular
Apalis/Colibri pins those GPIOs are on.

All boards with a SPI interface have a suitable spi alias except Apalis

bf78b2717d arm: tegra: initial support for apalis t30
This patch adds board support for the Toradex Apalis T30 a computer on
module which can be used on different carrier boards.

For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.

The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210
  fixes hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two
  ports as host)
