Currently there is no easy way to detect undervoltage conditions on a
remote Raspberry Pi. This hwmon driver retrieves the state of the
undervoltage sensor via mailbox interface. The handling based on
Noralf's modifications to the downstream firmware driver. In case of
an undervoltage condition only an entry is written to the kernel log.

Add Nuvoton BMC NPCM750/730/715/705 Pulse Width Modulation (PWM)
and Fan tacho driver.
The Nuvoton BMC NPCM750/730/715/705 supports 8 PWM controller outputs
and 16 Fan controller inputs.
The driver provides a sysfs entries through which the user can
configure the duty-cycle value from 0(off) and 255(full speed)
and read the fan tacho rpm value.

Driver obtains PWM and tachometers registers location according to the
system configuration and creates FAN/PWM hwmon objects and a cooling
device. PWM and tachometers are controlled through the on-board
programmable device, which exports its register map. This device could be
attached to any bus type, for which register mapping is supported. Single
instance is created with one PWM control, up to 12 tachometers and one
cooling device. It could be as many instances as programmable device
supports.
Currently driver will be activated from the Mellanox platform driver:
drivers/platform/x86/mlx-platform.c.
For the future ARM based systems it could be activated from the ARM
platform module.

Updated version of the ltc2990 driver which supports all measurement
modes (current, voltage, temperature) available in the chip.
If devicetree is used, the mode must be specified with the property
"lltc,meas-mode". The format and possible values of the property are
described in the binding.
If devicetree is not used, the mode of the chip will not be configured.
Unless the chip is configured by another source, only the internal
temperature and supply voltage will be measured.

The SMN (System Management Network) on Family 17h AMD CPUs is also accessed
from other drivers, specifically EDAC. Accessing it directly is racy.
On top of that, accessing the SMN through root bridge 00:00 is wrong on
multi-die CPUs and may result in reading the temperature from the wrong
die. Use available API functions to fix the problem.
For this to work, add dependency on AMD_NB. Also change the Raven Ridge
PCI device ID to point to Data Fabric Function 3, since this ID is used
by the API functions to find the CPU node.

Create a driver to add support for SoC sensors exported by the System
Control Processor (SCP) via the System Control and Management Interface
(SCMI). The supported sensor types is one of voltage, temperature,
current, and power.
The sensor labels and values provided by the SCP are exported via the
hwmon sysfs interface.

With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes
a link error:
drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe':
aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register'
This adds a dependency similar to what other hwmon drivers use,
ensuring that the aspeed driver cannot be built-in in this
case but has to be a module. With THERMAL=n, we still allow building it.
