Merge "ARM: tegra: Device tree changes for v4.1-rc1" from Thierry Reding:

A bunch of changes to improve support on the Nyan Big (Acer Chromebook
13). These enable the trackpad and make the WiFi card work. Changes to
the userspace-exposed name of the soundcard are required for a better
audio experience.

Support for Nyan Blaze (HP Chromebook 14) is added. It is very similar
to Nyan Big and therefore can enjoys many of the above improvements.

Since the EMC driver can now be used to scale the frequency at which
external memory is clocked, corresponding EMC frequency tables are added
for Jetson TK1 and the Nyan boards.

The Jetson TK1, Beaver and Nyan boards now also use generated pinmux
data, which makes it easier to keep it in sync with the data provided by
syseng.

NVIDIA Tegra Activity Monitor

The activity monitor block collects statistics about the behaviour of other
components in the system. This information can be used to derive the rate at
which the external memory needs to be clocked in order to serve all requests
from the monitored clients.

Required properties:
- compatible: should be "nvidia,tegra<chip>-actmon"
- reg: offset and length of the register set for the device
- interrupts: standard interrupt property
- clocks: Must contain a phandle and clock specifier pair for each entry in
clock-names. See ../../clock/clock-bindings.txt for details.
- clock-names: Must include the following entries:
- actmon
- emc
- resets: Must contain an entry for each entry in reset-names. See
../../reset/reset.txt for details.
- reset-names: Must include the following entries:
- actmon

Example:
actmon@6000c800 {
compatible = "nvidia,tegra124-actmon";
reg = <0x0 0x6000c800 0x0 0x400>;
interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&tegra_car TEGRA124_CLK_ACTMON>,
<&tegra_car TEGRA124_CLK_EMC>;
clock-names = "actmon", "emc";
resets = <&tegra_car 119>;
reset-names = "actmon";
};
