Paul Kocialkowski 5fc01a9909 ARM: tegra: nyan: Use external control for bq24735 charger
Nyan boards come with an embedded controller that controls when to
enable and disable the charge. Thus, it should not be left up to the
kernel to handle that.

Using the ti,external-control property allows specifying this use-case.

Paul Kocialkowski 38333641b6 ARM: tegra: nyan: Use proper IRQ type definitions
This switches a few interrupt definitions that were using
GPIO_ACTIVE_HIGH as IRQ type, which is invalid.

This is mostly a cosmetic change, that doesn't affect any driver.

posting initial Apalis TK1 support:

Please keep the remaining 0, notation on the GPU node in place as a
former mainline U-Boot version was looking for that particular notation
in order to perform required fix-ups on it.

Linus Torvalds 08344f3b43 ARM: SoC: late DT updates for v4.7
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The Renesas R-Car power domain handling, and the Nvidia Tegra USB
 support both hand notable changes that required changing the DT binding
 in a way that only provides compatibility with old DT blobs on new
 kernels but not vice versa. As a consequence, the DT changes
 are based on top of the driver changes and are now in this branch.
 
 For NXP i.MX and Samsung Exynos, the changes in here depend on
 other changes that got merged through the clk maintainer tree.

Sudeep Holla d1c04d30c3 ARM: tegra: Replace legacy *,wakeup property with wakeup-source
Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "nvidia,wakeup-source" boolean property to enable the
wakeup source, "wakeup-source" is the new standard binding.

This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any further copy-paste
duplication.

Jon Hunter 80373d37be ARM: tegra: Fix suspend hang on Tegra124 Chromebooks
Enabling CPUFreq support for Tegra124 Chromebooks is causing the Tegra124
to hang when resuming from suspend.

When CPUFreq is enabled, the CPU clock is changed from the PLLX clock to
the DFLL clock during kernel boot. When resuming from suspend the CPU
clock is temporarily changed back to the PLLX clock before switching back
to the DFLL. If the DFLL is operating at a much lower frequency than the
PLLX when we enter suspend, and so the CPU voltage rail is at a voltage
too low for the CPUs to operate at the PLLX frequency, then the device
will hang.

Please note that the PLLX is used in the resume sequence to switch the CPU
clock from the very slow 32K clock to a faster clock during early resume
to speed up the resume sequence before the DFLL is resumed.

Ideally, we should fix this by setting the suspend frequency so that it
matches the PLLX frequency, however, that would be a bigger change. For
now simply disable CPUFreq support for Tegra124 Chromebooks to avoid the
hang when resuming from suspend.
