9ca9a608a7 ARM: tegra: Add back gpio-ranges properties
The properties have been commented out to prevent a regression a while
ago. The first regression should be resolved by commit 44af792731
("spi: Map SPI OF client IRQ at probe time").

The second regression is probably addressed by commit 494fd7b7ad
("PM / core: fix deferred probe breaking suspend resume order") and/or
maybe others. Readd the gpio-ranges properties to see whether
regressions still get reported.

This reverts commit 4f1d841475 ("ARM: tegra: Comment out gpio-ranges
properties").

c6e331a2bb ARM: tegra: Avoid phandle indirection on Ouya
Move the default state pinmux definition into the pinmux node. There's
no need for the indirection via the phandle.

Note that the phandle indirection is kept for the EMC operating
performance point tables because they reference nodes that are defined
in an external file.

e3cc9c1c51 ARM: tegra: Remove stray #reset-cells property
The Ouya board specifies the #reset-cells property for the GPIO
controller. Since the GPIO controller doesn't provide reset controls
this is not needed, so they can be dropped.

c6d4a89775 ARM: tegra: Rename CPU and EMC OPP table device-tree nodes
OPP table name now should start with "opp-table" and OPP entries
shouldn't contain commas and @ signs in accordance to the new schema
requirement. Reorganize CPU and EMC OPP table device-tree nodes.

9ab9ecd83a ARM: tegra: Drop reg-shift for Tegra HS UART
When the Tegra High-Speed UART is used instead of the regular UART, the
reg-shift property is implied from the compatible string and should not

4c101a4466 ARM: tegra: ouya: Enable memory frequency thermal throttling using ACTMON
The ACTMON module monitors activity of memory clients and then devfreq
driver makes decisions about a required memory frequency based on info
from ACTMON. Add ACTMON device to the thermal zone of Ouya in order to
use it as a cooling device which throttles memory freq on overheat.

f8693f78f4 ARM: tegra: ouya: Specify all CPU cores as cooling devices
If CPU0 is unplugged the cooling device can not rebind to CPU1. And if
CPU0 is plugged in again, the cooling device may fail to initialize.

If the CPUs are mapped with the physical CPU0 to Linux numbering
CPU1, the cooling device mapping will fail.

Hence specify all CPU cores as a cooling devices in the device-tree.

3029a563ac ARM: tegra: ouya: Fix eMMC on specific bootloaders
Ouya fails to detect the eMMC module when booted via certain bootloaders.
Fastboot and hard-kexec bootloaders fail while u-boot does not. It was
discovered that the issue manifests if the sdmmc4 alternate configuration
clock pin is input disabled.

Ouya uses sdmmc4 in the primary pin configuration. It is unknown why this
occurs, though it is likely related to other eMMC limitations experienced
on Ouya.

For now, fix it by enabling input on cam_mclk_pcc0.

Add EMC OPP tables and interconnect paths that will be used for
dynamic memory bandwidth scaling based on memory utilization statistics.
Update board device-trees by removing unsupported EMC OPPs.

Note that ACTMON watches all memory interconnect paths, but we use a
single CPU-READ interconnect path for driving memory bandwidth, for
simplicity.

d7195ac5c9 ARM: tegra: Add device-tree for Ouya
The Ouya was the sole device produced by Ouya Inc in 2013.
It was a game console originally running Android 5 on top of Linux 3.1.10.

This patch adds the device tree supporting the Ouya.
It has been tested on the original variant with Samsung ram.
