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.

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.

Commit 274e43edcd ("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.

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.

The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC.
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
same IRQs as the AXP803, rather than the AXP288.

enabled.

Pull ARM SoC fixes from Olof Johansson:
"A couple of late-arriving fixes before final 4.13:
- A few reverts of DT bindings on Allwinner for their ethernet
driver. Discussion didn't converge, and since bindings are
considered ABI it makes sense to revert instead of having to
support two bindings long-term.
- A fix to enumerate GPIOs properly on Marvell Armada AP806"
