Alexandre Courbot 221b9bf42b ARM: tegra: roth: Fix SD card VDD_IO regulator
vddio_sdmmc3 is a vdd_io, and thus should be under the vqmmc-supply
property, not vmmc-supply.

Alexandre Courbot edbde56a25 ARM: tegra: Remove eMMC vmmc property for roth/tn7
This property was wrong and broke eMMC since commit 52221610d ("mmc:
sdhci: Improve external VDD regulator support"). Align the eMMC
properties to those of other Tegra boards.

Olof Johansson c4574aa00e ARM: dts: tegra: move serial aliases to per-board
There are general changes pending to make the /aliases/serial* entries
number the serial ports on the system. On Tegra, so far the ports have
been just numbered dynamically as they are configured so that makes them
change.

To avoid this, add specific aliases per board to keep the old numbers.
This allows us to change the numbering by default on future SoCs while
keeping the numbering on existing boards.

Alexandre Courbot 2236927d98 ARM: tegra: roth: add display DT node
Tegra DSI support has been fixed to support continuous clock behavior that
the panel used on SHIELD requires, so finally add its device tree node
since it is functional.

Alexandre Courbot 49f2747bb3 ARM: tegra: roth: enable input on mmc clock pins
Input had been disabled by mistake on these pins, leading to issues with
SDIO devices like the Wifi module not being probed or random errors
occuring on the SD card.

Alexandre Courbot 6982c07029 ARM: tegra: roth: fix unsupported pinmux properties
The pinmux subsystem complained that the nvidia,low-power-mode property
is not supported by the sdio1, sdio3 and gma drive groups. In addition
gma also does not support nvidia,drive-type. Remove these properties so
the pinmux configuration can properly be applied.

Alexandre Courbot e9d68f90df ARM: tegra: add device tree for SHIELD
NVIDIA SHIELD is a portable Android console containing a Tegra 4 SoC with
2GB RAM and a 720p panel.

The following hardware is enabled by this device tree: UART, eMMC, USB
(needs external power), PMIC, backlight, joystick, SD card, GPIO keys.

DSI panel, HDMI output, charger, self-powered USB, audio, wifi bluetooth
are not supported yet but might be by future patches (likely in that
order).

Touch panel and sensors will probably never be supported.

Initrd addresses are hardcoded to match the static values used by the
bootloader, since it won't add them for us. All the same, a kernel
command-line is provided to replace the one passed by the
bootloader which is filled with garbage.

NVIDIA SHIELD is typically booted with an appended DTB to avoid
modifications made by the bootloader.
