Add a CEC driver for the TDA9950, which is a stand-alone I2C CEC device,
but is also integrated into HDMI transceivers such as the TDA9989 and
TDA19989.
The TDA9950 contains a command processor which handles retransmissions
and the low level bus protocol. The driver just has to read and write
the messages, and handle error conditions.

Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs
- i.MX6SLL SoCs
Removed Drivers:
- ST-Ericsson AB8540/9540
Updates:
- Mediatek MT2701 and MT7622 audsys support and MT2712 updates
- STM32F469 DSI and STM32F769 sdmmc2 support
- GPIO clks can sleep now
- Spreadtrum SC9860 RTC clks
- Nvidia Tegra MBIST workarounds and various minor fixes
- Rockchip phase handling fixes and a memory leak plugged
- Renesas drivers switch to readl/writel from clk_readl/clk_writel
- Renesas gained CPU (Z/Z2) and watchdog support
- Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
- Qualcomm PM8921 PMIC XO buffers
- Amlogic migrates to regmap APIs
- TI Keystone clk latching support
- Allwinner H3 and H5 video clk fixes

This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.
The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.
Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.

mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it
is always one. On some x86 systems, other i2c drivers may probe before
i2c-mlxcpld, causing bus one to be busy.
Make mlx-platform determine which adapter number is free prior to
activating i2c-mlxpld, adjusting the mux base numbers accordingly.
Update the mlxreg-hotplug pdata similarly.
This adds an explicit mlx-platform build dependency on I2C, update the
Kconfig accordingly. Add the missing REGMAP dependency while we're at
it.

mlx-platform activates i2c-mux-reg, which creates buses needed by
mlxreg-hotplug. If the mlxreg-hotplug probe runs before the i2c-mux-reg
probe completes, it may attempt to connect a device to an adapter number
that has not been created yet, and fail.
Make mlx-platform driver record the highest bus number in mlxreg-hotplug
platform data and defer mlxreg-hotplug probe until all the buses are
created.

Pull ARM SoC platform updates from Arnd Bergmann:
"This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips in
mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older PXA
and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure is
needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected"

The "enable arbiter" bit is available only for pxa3xx based platforms
but it was experimentally shown that even if this bit is reserved,
some Marvell platforms (64-bit) actually need it to be set. The driver
always set this bit regardless of this property, which is harmless.
Then this property is not needed.
The "num_cs" field is always 1 and for a good reason, the old driver
(pxa3xx_nand.c) could only handle one. The new driver that replaces it
(marvell_nand.c) can handle more, but better use device tree for such
description. As there is only one available chip select, there is no
need for an array of partitions neither an array of partition numbers.

Pull "Driver changes for ti-sysc for v4.17" from Tony Lindgren:
This series of changes enables the use device tree based sysconfig
data for ti-sysc driver. As we already have SmartReflex data configured,
we use that as the first driver to enable. To do that in a way where
SmartReflex is not probed twice, we need to prepare the SmartReflex
driver before flipping dts data on for it in the last patch of the
series.
To avoid regressions, we are checking the passed dts data against
existing platform data since we still have it available. Then after the
dts files are converted, we can simply drop the related platform data
at some point in the future.

Now that ti-sysc can manage child devices, we must also be backwards
compatible with the current omap_device code. With omap_device, we
assume that the child device manages the interconnect target module
directly.
The drivers needing special handling are the ones that still set
pm_runtime_irq_safe(). In the long run we want to update those drivers
as otherwise they will cause problems with genpd as a permanent PM
runtime usage count is set on the parent device.
We can handle omap_device these devices by improving the ti-sysc quirk
handling to detect the devices needing special handling based on
register map and revision register if usable. We also need to implement
dev_pm_domain for these child devices just like omap_device does.

We want to pass the device tree configuration for interconnect target
modules from ti-sysc driver to the existing platform hwmod code.
This allows us to first validate the dts data against the existing
platform data before we start dropping the platform data in favor of
device tree data.
To do this, let's add platform data callbacks for PM runtime functions
to call for the interconnect target modules if platform data is
available.
Note that as ti-sysc driver can rebind, omap_auxdata_lookup and related
functions can no longer be __init.

Most of the PM code needed for am335x and am437x can be moved into a
module under drivers but some core code must remain in mach-omap2 at the
moment. This includes some internal clockdomain APIs and low-level ARM
APIs which are also not exported for use by modules.
Implement a few functions that handle these low-level platform
operations can be passed to the pm33xx module through the use of
platform data.
In addition to this, to be able to share data structures between C and
the sleep33xx and sleep43xx assembly code, we can automatically generate
all of the C struct member offsets and sizes as macros by processing
pm-asm-offsets.c into assembly code and then extracting the relevant
data as is done for the generated platform asm-offsets.h files.
Finally, add amx3_common_pm_init to create a dummy platform_device for
pm33xx so that our soon to be introduced pm33xx module can probe on
am335x and am437x platforms to enable basic suspend to mem and standby
support.

This converts from using a platform device for the CFGCHIP syscon
regmap to using platform data to pass the regmap to consumers.
A lazy getter function is used so that the regmap will only be
created if it is actually used. This function will also be used
in the clock init when we convert to the common clock framework.
The USB PHY driver is currently the only consumer. This driver is
updated to use platform data to get the CFGCHIP regmap instead of
syscon_regmap_lookup_by_pdevname().

"This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of depending on
it. This is merged with the same pattern for all the ISA drivers
and some other Kconfig cleanups related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of this SoC
from the ARM tree.
- Move the documentation over to driver-api to conform with the rest
of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we
want to get rid of.

"AT24 updates for 4.16 merge window
The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.
Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).
We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.
Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."

Some multi-address eeproms in the at24 family may not automatically
roll-over reads to the next slave address. On those eeproms, reads
that straddle slave boundaries will not work correctly.
Solution:
Mark such eeproms with a flag that prevents reads straddling
slave boundaries. Add the AT24_FLAG_NO_RDROL flag to the eeprom
entry in the device_id table, or add 'no-read-rollover' to the
eeprom devicetree entry.
Note that I have not personally enountered an at24 chip that
does not support read rollovers. They may or may not exist.
However, my hardware requires this functionality because of
a quirk.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The core framework has a handful of patches this time around, mostly
due to the clk rate protection support added by Jerome Brunet.
This feature will allow consumers to lock in a certain rate on the
output of a clk so that things like audio playback don't hear pops
when the clk frequency changes due to shared parent clks changing
rates. Currently the clk API doesn't guarantee the rate of a clk stays
at the rate you request after clk_set_rate() is called, so this new
API will allow drivers to express that requirement.
Beyond this, the core got some debugfs pretty printing patches and a
couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h
file causes small one-liners in all the architecture Kbuild files.
Overall, the driver diff seems to be the normal stuff that comes all
the time to fix little problems here and there and to support new
hardware.
Summary:
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs"

We can easily detect i2c based on it's non-standard module registers that
consist of two 32-bit registers accessed in 16-bit mode.
So far we don't have other 16-bit modules, so there's currently no need
to add a custom property for 16-bit register access.

Let's add data for the known interconnect target module types by mapping

Note that we can handle many quirks for the older omap2 type1 modules
