The IPQ8064 also includes an RPM following the same message structure as
other chips. In addition, it supports a few new resource types to
support the NSS fabric clocks and the SMB208/SMB209 regulators found on
the reference boards.

Since commit 6e3f62f079 ("mfd: core: Fix platform-device id
generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when
registering mfd-devices.
Unfortunately, some mfd-drivers rely on the old behaviour of generating
platform-device ids by adding the cell id also to the special value of
PLATFORM_DEVID_NONE. The resulting platform ids are not only used to
generate device-unique names, but are also used instead of the cell id
to identify cells when probing subdevices.
These drivers should be updated to use PLATFORM_DEVID_AUTO, which would
also allow more than one device to be registered without resorting to
hacks (see for example wm831x), but lets fix the regression first by
partially reverting the above mentioned commit with respect to
PLATFORM_DEVID_NONE.

dmi_get_system_info() may return NULL either when CONFIG_DMI is not set or when
board has an old firmware. The patch prevents a crash and changes the default

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
OK but msecs_to_jiffies(val) is the cleaner solution and handles all
corner cases correctly. This is a minor API consolidation only and
should make things more readable.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

In Quark X1000, there's a single PCI device that provides both
an I2C controller and a GPIO controller. This MFD driver will
split the 2 devices for their respective drivers.
This patch is based on Josef Ahmad's initial work for Quark enabling.

Rk808 has a under voltage detect function, when the voltage of buck is
under 85% the target voltage, the buck output will reset. But if the
power load is too heavy, this function maybe err, when current over
4.2A, although the voltage is normal, but RK808 mistakenly think it is
under 85%, and reset the buck. So let's disable this function.

The range of registers used by this driver exceeds that available
via SPI with no paging (127), so we have to override the values
from the default config which is set-up for I2C access.
Also change SPI settings to match device's recommended OTP values.

This adds support for the MediaTek MT6397 PMIC. This is a
multifunction device with the following sub modules:
- Regulator
- RTC
- Audio codec
- GPIO
- Clock
It is interfaced to the host controller using SPI interface by a proprietary
hardware called PMIC wrapper or pwrap. MT6397 MFD is a child device of the
pwrap.
