Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly
are driver updates (including a major consolidation of intel_pstate),
some schedutil governor modifications and core cleanups.There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.The rest is a few cpuidle changes (nothing major), devfreq updates,
generic power domains (genpd) framework updates and a few assorted
modifications elsewhere.Specifics:
- Drop the P-state selection algorithm based on a PID controller from
intel_pstate and make it use the same P-state selection method
(based on the CPU load) for all types of systems in the active mode
(Rafael Wysocki, Srinivas Pandruvada).- Rework the cpufreq core and governors to make it possible to take
cross-CPU utilization updates into account and modify the schedutil
governor to actually do so (Viresh Kumar).- Clean up the handling of transition latency information in the
cpufreq core and untangle it from the information on which drivers
cannot do dynamic frequency switching (Viresh Kumar).- Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
cpufreq driver and update its DT bindings (Sean Wang).- Modify the cpufreq dt-platdev driver to autimatically create
cpufreq devices for the new (v2) Operating Performance Points (OPP)
DT bindings and update its whitelist of supported systems (Viresh
Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
Xiao).- Add support for Ux500 to the cpufreq-dt driver and drop the
obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).- Update the IO-wait boost handling in the schedutil governor to make
it less aggressive (Joel Fernandes).- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).- Update documentation related to system sleep and rename a number of
items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).- Clean up the cpuidle subsystem to handle the polling state on x86
in a more straightforward way and to use %pOF instead of full_name
(Rafael Wysocki, Rob Herring).- Update the devfreq framework to fix and clean up a few minor issues
(Chanwoo Choi, Rob Herring).- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).- Fix and clean up a couple of issues in the operating performance
points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).- Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
(AVS) driver (David Wu).- Fix the usage of notifiers in CPU power management on some
platforms (Alex Shi).- Update the pm-graph system suspend/hibernation and boot profiling
utility (Todd Brandt).- Make it possible to run the cpupower utility without CPU0 (Prarit

Both Bay and Cherry Trail devices may be used together with a Crystal Cove
PMIC. Each platform has its own variant of the PMIC, which both use the
same ACPI HID, but they are not 100% compatible.This commits makes the intel_soc_pmic_core code check the _HRV of the
ACPI-firmware-node and selects intel_soc_pmic_config_byt_crc resp.
intel_soc_pmic_config_cht_crc based on this.This fixes the Bay Trail specific ACPI OpRegion code causing problems
on Cherry Trail devices. Specifically this was causing the external
microsd slot on a Dell Venue 8 5855 (Cherry Trail version) to not work
and the eMMC to become unreliable and throw lots of errors.Fixes: 5165238460 ("mfd: intel_soc_pmic: Core driver")

Both Bay and Cherry Trail devices may be used together with a Crystal Cove
PMIC. Each platform has its own variant of the PMIC, which both use the
same ACPI HID, but they are not 100% compatible.Looking at the android x86 kernel sources where most of the Crystal Cove
code comes from, it talks about "Valley View", "Bay Trail" and / or BYT
without ever mentioning Cherry Trail, with the exception of the regulator
driver. The Asus Zenfone-2 kernel code has 2 regulator drivers, one
for Crystal Cove and one for what it calls Crystal Cove Plus. The
Crystal Cove Plus regulator driver is the only one to mention Cherry
Trail and that driver uses different register addresses then the
normal (Bay Trail) Crystal Cove regulator driver, showing that at
least the regulator register addresses are different.The GPIO code should work on both, and the PWM code is known to work on
both and is necessary for backlight control on some Cherry Trail devices.Testing has shown that the ACPI OpRegion code otoh is causing problems
on Cherry Trail devices, which is not surprising as it deals with the
regulators and those have different register addresses on CHT.Specifically the ACPI OpRegion code causes the external microsd slot on
a Dell Venue 8 5855 (Cherry Trail version) to not work and the eMMC to
become unreliable and throw lots of errors.This commit replaces the single mfd_cell array currently used for Crystal
Cove with 2 separate arrays, one for the Bay Trail variant and one for
the Cherry Trail variant, note that the Cherry Trail version of the array
only contains gpio and pwm cells. The PMIC OpRegion cell is deliberately
not included and drivers for the other cells in the Bay Trail cell array
were never upstreamed.Fixes: 7cf0a66f32 ("mfd: intel_soc_pmic: Crystal Cove support")

Commit 274e43edcda6f ("mfd: intel-lpss: Do not put device in reset
state on suspend") changed the behavior on suspend by not putting LPSS
controllers into reset. This was done because S3/S0ix fail if UART
device is put into reset and no_console_suspend flag is enabled.Because of the above change, I2C controller gets into a bad state if
it observes that the I2C lines are pulled low when power to I2C device
is cut off during suspend (generally, I2C lines are pulled to power
rail of the I2C device in order to ensure that there is no leakage
because of the pulls when device is turned off). This results in the
controller timing out for all future I2C operations after resume. It
is primarily because of the following sequence of operations:During suspend:
1. I2C controller is disabled, but it is not put into reset.
2. Power to I2C device is cut off.
3. #2 results in the I2C lines being pulled low.==> At this point the I2C controller gets into a bad state
On resume:
1. Power to I2C device is enabled.
2. #2 results in the I2C lines being pulled high.
3. I2C controller is enabled.However, even after enabling the I2C controller, all future I2C xfers
fail since the controller is in a bad state and does not attempt to
make any transactions and hence times out.In order to ensure that the controller does not get into a bad state,
this change puts it into reset if the controller type is not
UART. With this change, the order of operations is:During suspend:
1. I2C controller is disabled and put into reset.
2. Power to I2C device is cut off.
3. #2 results in the I2C lines being pulled low.On resume:
1. Power to I2C device is enabled.
2. #2 results in the I2C lines being pulled high.
3. I2C controller is enabled and taken out of reset.Signed-off-by: Furquan Shaikh

At least on Lenovo Thinkpad Yoga, the BIOS seems to monitor the SPI-NOR
write protection bit and if it is flipped to read/write it assumes the
BIOS configuration was changed on next reboot. It then, for unknown
reasons, resets the BIOS settings back to default.We can prevent this by just leaving the write protection bit intact and
let the SPI-NOR driver know whether the device is writable or not. In
case of this particular Lenovo the SPI-NOR flash will be exposed as
read-only.Fixes: ff00d7a32a1b ("mfd: lpc_ich: Add support for SPI serial flash host controller")

It has the same range of functions as other X-Powers PMICs, such as
DC-DC buck converter and linear regulator outputs, AC-IN and VBUS
power supplies, power button trigger, GPIOs, ADCs, and a battery
charger.Note that the IRQ table given in the datasheet is incorrect: in IRQ
enable/status registers 1, there are separate IRQs for ACIN and VBUS,
instead of bits [7:5] being the same as bits [4:2]. So it shares the

The ARMSS clock, also known as the operating point of the
CPU, should not cross-depend on cpufreq like this. Move
the code to use just frequencies and remove the false
frequency (1GHz) and put in the actual frequency provided
by the ARMSS clock (998400000 Hz) as part of the process.After this and the related cpufreq patch, the DB8500 will
simply use the standard DT cpufreq driver to change the
operating points through the common clock framework using
the ARMSS clock.Acked-by: Lee Jones

If the touchscreen pins are used as general purpose analogue
input, the touchscreen driver should not be used. The pins
will be handled by the existing hwmon driver instead.Signed-off-by: Sebastian Reichel
