This is a collection of a few late fixes and other misc. stuff that
had dependencies on things being merged from other trees.
The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates.
There's one conflict with drivers/cpufreq/exynos-cpufreq.c because
it's now been completely removed, but there were some fixes that hit
mainline in the meantime.

Commit d5e136a21b ("clk: samsung: Register

modified a way that driver registers registers to core framework. This
change has not been applied to s5pv210 clocks driver, which has been
merged in parallel to that commit. This patch adds a missing call to
samsung_clk_of_add_provider(), so the driver is operational again.

The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver.
However TSADC is present only on Exynos4210 so on Trats2 board (with
Exynos4412 SoC) the exynos-adc driver could not be probed:
ERROR: could not get clock /adc@126C0000:adc(0)
exynos-adc 126c0000.adc: failed getting clock, err = -2
exynos-adc: probe of 126c0000.adc failed with error -2
Instead on Exynos4x12 SoCs the main clock used by Analog to Digital
Converter is located in different register and it is named in datasheet
as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock
is the same as purpose of TSADC from Exynos4210.
The patch adds gate clock for Exynos4x12 using the proper register so
backward compatibility is preserved. This fixes the probe of exynos-adc
driver on Exynos4x12 boards and allows accessing sensors connected to it
on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Only include clk.h in files that are
using it. The clkdev.h header isn't always used either, so remove
it and add in slab.h where files were relying on it to include
slab for them.

Changes by Bartlomiej:
- fixed issue with wrong dividers being setup by Common Clock Framework
(by an addition of CLK_RECALC_NEW_RATES clock flag to mout_apll clock,
without this change cpufreq-dt driver showed ~10 mA larger energy
consumption when compared to cpufreq-exynos one when "performance"
cpufreq governor was used on Exynos4210 SoC based Origen board), this
was probably meant to be workarounded by use of CLK_GET_RATE_NOCACHE
and CLK_DIVIDER_READ_ONLY clock flags in the original patchset (in
"[PATCH v12 6/6] clk: samsung: remove unused clock aliases and update
clock flags") but using these flags is not sufficient to fix the issue
observed

The CPU clock provider supplies the clock to the CPU clock domain. The
composition and organization of the CPU clock provider could vary among
Exynos SoCs. A CPU clock provider can be composed of clock mux, dividers
and gates. This patch defines a new clock type for CPU clock provider and
adds infrastructure to register the CPU clock providers for Samsung
platforms.
Changes by Bartlomiej:
- fixed issue with setting lower dividers before the parent clock speed
was lowered (the issue resulted in lockup on Exynos4210 SoC based
Origen board when "ondemand" cpufreq governor was stress tested)
- fixed missing spin_unlock on error in exynos_cpuclk_post_rate_change()
problem by moving cfg_data search outside of the spin locked area
- removed leftover kfree() in exynos_register_cpu_clock() that could
result in dereferencing the NULL pointer on error
- moved spin_lock earlier in exynos_cpuclk_pre_rate_change() to cover
reading of E4210_SRC_CPU and E4210_DIV_CPU1 registers
- added missing "last chance" checks to wait_until_divider_stable() and
wait_until_mux_stable() (needed in case that IRQ handling took long
time to proceed and resulted in function printing incorrect error
message about timeout)
- moved E4210_CPU_DIV[0,1]() macros just before their only users,
this resulted in moving them from patch #2 to patch #3/6 ("clk:
samsung: exynos4: add cpu clock configuration data and instantiate
cpu clock")
- removed E5250_CPU_DIV[0,1](), E5420_EGL_DIV0() and E5420_KFC_DIV()
macros for now
- added my Copyrights to drivers/clk/samsung/clk-cpu.c

Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power
Management support v12") added pm support for the pl330 dma driver but
it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated
during suspend and this in turn makes its parent clock aclk266_g2d to
be gated. But the clock needs to be ungated prior suspend to allow the
system to be suspend and resumed correctly.
Add GATE_BUS_TOP register to the list of registers to be restored when
the system enters into a suspend state so aclk266_g2d will be ungated.
Thanks to Abhilash Kesavan for figuring out that this was the issue.

enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices. Additionaly the framework core underwent a bit of surgery with
two major changes. The boundary between the clock core and clock
providers (e.g clock drivers) is now more well defined with dedicated
provider helper functions. struct clk no longer maps 1:1 with the
hardware clock but is a true per-user cookie which helps us tracker
users of hardware clocks and debug bad behavior. The second major change
is the addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the regulator
framework. Unfortunately these changes to the core created some
breakeage. We think we fixed it all up but for this reason there are
lots of last minute commits trying to undo the damage.

Merge tag 'clk-for-linus-3.20' of git://git.linaro.org/people/mike.turquette/linux
Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

Merge tag 'v3.20-exynos-clk' of git://linuxtv.org/snawrocki/samsung into clk-next
Exynos 3250, 4415 drivers cleanup by using common code
and addition of clock definitions for DVFS on Exynos4.
When a power domain is powered off on Exynos5420 SoC, the input clocks of
the devices attached to this power domain are re-parented to oscclk and
restored to the original parent after powering on the power domain.
So a reference to the input and parent clocks for the devices attached to
a power domain are needed to be able to do the re-parenting. The DISP1 pd
includes modules which uses the following clocks:
ACLK_200_DISP1 (MIXER and HDMILINK)
ACLK_300_DISP1 (FIMD1)
ACLK_400_DISP1 (Internal Buses)
Each of these clocks are generated as the output of a clock mux so add an
ID for all of these clock muxes and their parents to be referenced in the
DISP1 power domain device node.

Audio subsystem clocks are located in separate block. On Exynos 5420 if
clock for this block (from main clock domain) 'mau_epll' is gated then
any read or write to audss registers will block.
This kind of boot hang was observed on Arndale Octa and Peach Pi/Pit
after introducing runtime PM to pl330 DMA driver. After that commit the
'mau_epll' was gated, because the "amba" clock was disabled and there
were no more users of mau_epll.
The system hang on one of steps:
1. Disabling unused clocks from audss block.
2. During audss GPIO setup (just before probing i2s0 because
samsung_pinmux_setup() tried to access memory from audss block which was
gated.
Add a workaround for this by enabling the 'mau_epll' clock in probe.

to PLL46xx with minor differences in bit positions. Hence,
reuse the functions defined for pll_35xx and pll_46xx to
support 145xx and 1460x PLLs respectively.

sclk_g3d clock doesn't have enable/disable bits, but the driver hijacked
g3d gate clock bits for this purpose and didn't provide real g3d clock
at all. This patch fixes this issue by adding proper definition for g3d
clock and removing incorrect access to GATE_IP_G3D register in sclk_g3d.
In addition CLK_SET_RATE_PARENT flag is dropped from sclk_g3d, because
it does not make any sense and most likely has been added by mistake.

Enable ARMCLK down feature on all Exynos4 SoCs. The frequency of
ARMCLK will be reduced upon entering idle mode (WFI or WFE).
The feature behaves like very fast cpufreq ondemand governor. In idle
mode this reduces energy consumption on full frequency chosen by
cpufreq governor by approximately:
- Trats2: 6.5% (153 mA -> 143 mA)
- Trats: 33.0% (180 mA -> 120 mA)
- Gear1: 27.0% (180 mA -> 130 mA)
The patch uses simillar settings as Exynos5250 (clk-exynos5250.c),
except it disables clock up feature and on Exynos4412 ARMCLK down is
enabled for all 4 cores.

The "aclk66_peric" clock is a gate clock with a whole bunch of gates
underneath it. This big gate isn't very useful to include in our
clock tree. If any of the children need to be turned on then the big
gate will need to be on anyway. ...and there are plenty of other "big
gates" that aren't described in our clock tree, some of which shut off
collections of clocks that have no relationship in the hierarchy so
are hard to model.
"aclk66_peric" is causing earlyprintk problems since it gets disabled
as part of the boot process, so let's just remove it.
Strangely (and for no good reason) this clock is exported as part of
the common clock bindings. Remove it since there are no in-kernel
device trees using it and no reason anyone out of tree should refer to
it either.

In the move to this clock driver the hookups for the SPI clocks were
dropped, which causes my system Cragganmore (s3c6410 based) to be unable
to locate any spibus clocks. This patch adds them back in.
When taking the clock from the epll clock (SCLK) the rates on the SPI
bus are incorrect, this needs further debugging but the hookup here
should be correct and the problem should be else where.
The USBCLK case has been dropped because this requires the USB PHY to be
enabled.

SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing lists),
we are here adding a drivers/soc directory. The purpose of this is
to keep per-vendor shared code that's needed by different drivers but
that doesn't fit into the MFD (nor drivers/platform) model. We expect
to keep merging contents for this hierarchy through arm-soc so we can
keep an eye on what the vendors keep adding here and not making it a
free-for-all to shove in crazy stuff.

Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock
defined exactly in same way in documentation. Using different
names for these clocks is a bit misleading. Since there is no users
of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and
replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA
has correct clock assigned on Exynos4x12 SoCs.

Samsung CCF helper functions do not provide support to
register multiple Clock Providers for a given SoC. Due to
this limitation, SoC platforms are not able to use these
helpers for registering multiple clock providers and are
forced to bypass this layer.
This layer is modified accordingly to enable the support
for multiple clock providers.

This driver can handle the clock controllers of the socs mentioned above,
as they share a common clock tree with only small differences.
The clock structure is built according to the manuals of the included
SoCs and might include changes in comparison to the previous clock
structure.
As pll-rate-tables only the 12mhz variants are currently included.
The original code was wrongly checking for 169mhz xti values [a 0 to much
at the end], so the original 16mhz pll table would have never been
included and its values are so obscure that I have no possibility to
at least check their sane-ness. When using the formula from the manual
the resulting frequency is near the table value but still slightly off.

This adds a driver for controlling the external clock outputs of
s3c24xx architectures including the dclk muxes and dividers.
The driver at the moment only supports the legacy non-dt boards using these
clock outputs. The clock-output control itself is part of the system-controller
mainly controlled by the pinctrl drivers. So it should most likely be
integrated there for dt platforms.

The three SoCs share a common clock tree which only differs in the
existence of some special clocks.
As with all parts common to these three SoCs the driver is named
after the s3c2443, as it was the first SoC introducing this structure
and there exists no other label to describe this s3c24xx epoch.
The clock structure is built according to the manuals of the included

the pll_6552 differs to the one from the s3c64xx series.
The change is solely in the bit locations of the mdiv and pdiv values.
All calculations are the same for both implementatons and even the
proposed divider-values for specific frequencies in the manuals are
the same.
Therefore implement a variant that simply uses the changed bit

The Exynos AudioSS clock controller will later be modified to allow
input clocks to be specified via device-tree in order to support
multiple Exynos SoCs. This will introduce a dependency on the core
SoC clock controller being initialized first so that the AudioSS driver
can look up its input clocks, but the order in which clock providers
are probed in of_clk_init() is not guaranteed. Since deferred probing
is not supported in of_clk_init() and the AudioSS block is not the core
controller, we can initialize it later as a platform device.
