Introduce SENSOR_DEVICE_ATTR_{RO,RW,WO} and SENSOR_DEVICE_ATTR_2_{RO,RW,WO}
as simplified variants of SENSOR_DEVICE_ATTR and SENSOR_DEVICE_ATTR_2 to
simplify the source code, improve readbility, and reduce the chance of
inconsistencies.

The STLM75 is a high-precision digital CMOS temperature sensor
IC with a sigma-delta temperature-to-digital converter.
The configuration register mapping is similar to existing lm75
but the sample rate is 150ms(max).
Tested on real hardware and verified temperature readings are correct.

If all three channels are disabled via in[123]_enable ABI,
the driver could suspend the chip for power saving purpose.
So this patch adds the PM runtime support in order to gain
more power control than system suspend and resume use case.
For PM runtime, there are a few related changes happening:
1) Added a new pm_dev device pointer for all the PM runtime
callbacks. This is because hwmon core registers a child
device for each hwmon driver and passes it back to each
driver. So there might be a mismatch between two device
pointers in the driver if mixing using them.
2) Added a check in ina3221_is_enabled() to make sure that
the chip is resumed.
3) Bypassed the unchanged status in ina3221_write_enable()
in order to keep the PM runtime refcount being matched.
4) Removed the reset routine in the probe() by calling the
resume() via pm_runtime_get_sync() instead, as they're
similar. It's also necessary to do so to match initial
PM refcount with the number of enabled channels.

The data might need some time to get ready after channel enabling,
although the data register is always readable. The CVRF bit is to
indicate that data conversion is finished, so polling the CVRF bit
before data reading could ensure the result being valid.
An alternative way could be to wait for expected time between the
channel enabling and the data reading. And this could avoid extra
I2C communications. However, INA3221 seemly takes longer time than
what's stated in the datasheet. Test results show that sometimes
it couldn't finish data conversion in time.
So this patch plays safe by adding a CVRF polling to make sure the
data register is updated with the new data.

This change adds a mutex to serialize accesses of sysfs attributes.
This is required when polling CVRF bit of the MASK/ENABLE register
because this bit is cleared on a read of this MASK/ENABLE register
or a write to CONFIG register, which means that this bit might be
accidentally cleared by reading other fields like alert flags.
So this patch adds a mutex lock to protect the write() and read()
callbacks. The read_string() callback won't need the lock since it
just returns the label without touching any hardware register.

There is nothing critically wrong to read these two attributes
without having a is_enabled() check at this point. But reading
the MASK_ENABLE register would clear the CVRF bit according to
the datasheet. So it'd be safer to fence for disabled channels
in order to add pm runtime feature.

The OCC provides a variety of additional information about the state of
the host processor, such as throttling, error conditions, and the number
of OCCs detected in the system. This information is essential to service
processor applications such as fan control and host management.
Therefore, export this data in the form of sysfs attributes attached to
the platform device (to which the hwmon device is also attached).

Add method to parse the response from the OCC poll command. This only

number and version of sensors, which we need to instantiate hwmon
attributes.

The OCC is a device embedded on a POWER processor that collects and
aggregates sensor data from the processor and system. The OCC can
provide the raw sensor data as well as perform thermal and power
management on the system.
This driver provides a hwmon interface to the OCC from a service
processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs.
Communications with the POWER8 OCC are established over standard I2C
bus. The driver communicates with the POWER9 OCC through the FSI-based
OCC driver, which handles the lower-level communication details.
This patch lays out the structure of the OCC hwmon driver. There are two
platform drivers, one each for P8 and P9 OCCs. These are probed through
the I2C tree and the FSI-based OCC driver, respectively. The patch also
defines the first common structures and methods between the two OCC
versions.

provide the raw sensor data as well as perform thermal and power
management on the system.
This driver provides an atomic communications channel between a service

SBEFIFO driver to get hardware access through the SBE to the OCC SRAM.
Commands are issued to the SBE to send or fetch data to the SRAM.

As per the usual standard with hwmon drivers the mapping to sysfs
entries follows the register map of the device e.g. in0_input
corresponds to the register 0x20, in1_input corresponds to 0x21 etc.
Hardware designers tend to work with input pins instead of registers
which is where things start to get confusing. A hardware designer might
say "the 1.5V rail is connected to the VCCP pin" leaving the software
designer none the wiser as to which of the sysfs entries should be
associated with the label "1.5V".
Try to bridge the gap by documenting the mapping of sysfs entries to
the corresponding pins. This should allow someone to create a
configuration file or other mapping without needing to dive into the
code and ADT datasheets.

The ADM series of hotswap controllers support extending
the current measurement range by using a sensing resistor
value other than the typical 1 mOhm. For example, using a 0.5 mOhm
sensing resistor doubles the maximal current can be measured.
Current driver assumes a shunt resistor value of 1 mOhm in calculation,
meaning for other resistor values, hwmon will report scaled
current/power measurements. This patch parses device tree parameter
"shunt-resistor-micro-ohms", if there is one.

- Disable STIBP automatically when SMT is disabled
- Optimize the switch_to() logic to avoid MSR writes and invocations

The macros PCI_EXP_LNKCAP_SLS_*GB are values, not bit masks. We must mask

6cf57be0f78e, which appeared in v4.17, added pcie_get_speed_cap() with the
incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask. 5d9a63304032, which

The linux-mips.org infrastructure has been unreliable recently & nobody
with sufficient access to fix it is around to do so. As a result we're
moving away from it, and part of this is migrating our mailing list to
kernel.org.
Replace all instances of linux-mips@linux-mips.org in MAINTAINERS with
the shiny new linux-mips@vger.kernel.org address.
The new list is now being archived on kernel.org at
https://lore.kernel.org/linux-mips/ which also holds the history of the
old linux-mips.org list.
