Pull ARM DT updates from Olof Johansson:
"As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a
crisp overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes"

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"

clk: tegra: Changes for v4.5-rc1
This set of changes adds support for the Tegra210 SoC and contains a
couple fixes and cleanups.

When the clock DT property is not given, of_clk_get_parent_count()
returns -ENOENT, which then tries to allocate -2 x 4 bytes of memory,
which of course fails, causing the whole driver to fail to create
the clock.
This causes the SolidRun platforms to fail probing the SDHCI1 interface
which is connected to the WiFi.
Fix this by detecting errno codes, skipping the allocation, and fixing
of_clk_gpio_gate_delayed_register_get() to handle a NULL parent_names
array.

To model the muxes downstream of fractional dividers we introduced the
child property, allowing to describe a direct child clock.
The first implementation seems to cause section warnings, as the core
clock-tree is marked as initdata while the data pointed to from the
child element is not.
While there may be some way to also set that missing property in the
inline notation I didn't find it, so to actually fix the issue for now
move the sub-definitions into separate declarations that can have
their own __initdata properties.

Pull "reworked dts changes for ti81xx devices and minimal
dra62x j5ec-evm support" from Tony Lindgren:
Add minimal device tree support for dra62x also known j5eco. It is
related to dm814x, just the clocks are a bit different and it has a
different set of integrated devices. And let's get some basic dm814x
and dra62x devices working as many of the devices are like on am33xx::
- pinctrl using the pinctrl defines as for am33xx
- Updated EDMA bindings with support for using exma_xbar
- MMC support for dm814x-evm, t410 and dra62x-j5eco-evm
- USB support for dm814x-evm, t410 and dra62x-j5eco-evm
This branch depends on an earlier omap-for-v4.5/81xx-fixes-signed
branch that has dm814x dts fixes interlaced with SoC related fixes to
keep things booting. The interlaced SoC and dts fixes were needed
because of issues with the device tree defined clocks that just
happened to work on bootloader timings for t410 earlier.

Some bcm2835 clocks used by hardware (like "PWM" or "H264") can have multiple
parent clocks. These clocks divide the rate of a parent which can be selected by
setting the proper bits in the clock control register.
Previously all these parents where handled by a mux clock. But a mux clock
cannot be used because updating clock control register to select parent needs a
password to be xor'd with the parent index.
This patch get rid of mux clock and make these clocks handle their own parent,
allowing them to select the one to use.

Some clocks need to be enabled to accept rate changes. This patch adds a
new flag CLK_SET_RATE_UNGATE that lets clk_change_rate enable the clock

This of course doesn't effect clocks that are already running at that
point, as their refcount will only temporarily increase.

The fractional dividers of Rockchip SoCs contain an "auto-gating-feature"
that requires the downstream mux to actually point to the fractional
divider and the fractional divider gate to be enabled, for it to really
accept changes to the divider ratio.
The downstream muxes themselfs are not generic enough to include them
directly into the fractional divider, as they have varying sources of
parent clocks including not only clocks related to the fractional
dividers but other clocks as well.
To solve this, allow our clock branches to specify direct child clock-
branches in the new child property, let the fractional divider register
its downstream mux through this and add a clock notifier that temporarily
switches the mux setting when it notices rate changes to the fractional
divider.

As commit 1d33929e2a2b ("clk: rockchip: switch PLLs to slow mode before
reboot for rk3288") states, switching the PLLs to slow-mode is only
necessary when rebooting using the soft-reset done through the CRU.
The dwc2 controllers used create really big number of interrupts in
special constellations involving usb-hubs and their number is so high,
it can even overwhelm the interrupt handler if the cpu-speed os to low.
Right now the PLLs are put into slow-mode in a shutdown syscore_ops
callback which means it happens on all reboots (not only the soft-reset
ones) and even on poweroff actions.
This can result in the system not powering off and getting stuck instead,
so we should move the slow-mode change nearer to the actual reboot action.
For this we introduce the possiblity to also set a callback that gets
called from the restart-handler directly prior to restarting the system
and move the shutdown-callback to this new option.
With this the slow-mode switch is done only on the necessary reboots
and also has a smaller possibility of causing artifacts.

including both causes a build-time error.
I'm doing an evil merge here to pull in the fixes branch so we have
that commit included but at the same time revert the trivial change.
This gives us a bisectable history.

This fixes a bug in tegra_clk_register_pllss() which mistakenly assume
the IDDQ register is the PLL base address.

This fixes two things.
- Read the correct IDDQ register
- Check the correct IDDQ bit position

Without this change clk_get_rate would return the final output
rather than the VCO output as it would factor in the pdiv when
it shouldn't. This will cause problems for all dividers in the
subtree of the VCO PLL.

Super clock divider control and clock source mux of Tegra210 has changed
a little against prior SoCs, this patch adds Gen5 logic to address those
differences.

Add some logic for Spread Spectrum control. It is used in conjuncture
with SDM fractional dividers. SSC has to be disabled when we configure
the divider settings.
