This commit adds support for Ampere SMpro hwmon driver. This driver
supports accessing various CPU sensors provided by the SMpro co-processor
including temperature, power, voltages, and current.

Thanks Guenter for picking the patches.
There are two issues found by Bagas [1] in document format and kernel
test robot [2] on smpro-hwmon.c. I'll fix them in separate patches.

+Kernel driver Ampere(R)'s Altra(R) SMpro hwmon
+==============================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Reference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+This driver supports hardware monitoring for Ampere(R) Altra(R) SoC's based on the
+SMpro co-processor (SMpro).
+The following sensor types are supported by the driver:
+
+ * temperature
+ * voltage
+ * current
+ * power
+
+The SMpro interface provides the registers to query the various sensors and
+their values which are then exported to userspace by this driver.
+
+Usage Notes
+-----------
+
+SMpro hwmon driver creates at least two sysfs files for each sensor.
+
+* File ``<sensor_type><idx>_label`` reports the sensor label.
+* File ``<sensor_type><idx>_input`` returns the sensor value.
+
+The sysfs files are allocated in the SMpro root fs folder.
+There is one root folder for each SMpro instance.
+
+When the SoC is turned off, the driver will fail to read registers
+and return -ENXIO.
+
+Sysfs entries
+-------------
+
+The following sysfs files are supported:
+
+* Ampere(R) Altra(R):

It is documented under the entry for the
"/sys/bus/platform/devices/smpro-errmon.*/overflow_[core|mem|pcie|other]_[ce|ue]"
in the [9/9] patch.

I'll follow this suggestion in next version.

+Kernel driver Ampere(R)'s Altra(R) SMpro errmon
+===============================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Preference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+
+This driver supports hardware monitoring for Ampere(R) Altra(R) SoC's based on the
+SMpro co-processor (SMpro).
+The following SoC alert/event types are supported by the errmon driver:
+
+* Core CE/UE error
+* Memory CE/UE error
+* PCIe CE/UE error
+* Other CE/UE error
+* Internal SMpro/PMpro error
+* VRD hot
+* VRD warn/fault
+* DIMM Hot
+
+The SMpro interface provides the registers to query the status of the SoC alerts/events
+and their data and export to userspace by this driver.
+
+The SoC alerts/events will be referenced as error below.
+
+Usage Notes
+-----------
+
+SMpro errmon driver creates the sysfs files for each error type.
+Example: ``error_core_ce`` to get Core CE error type.
+
+* If the error is absented, the sysfs file returns empty.
+* If the errors are presented, one each read to the sysfs, the oldest error will be returned and clear, the next read will be returned with the next error until all the errors are read out.
+
+For each host error type, SMpro keeps a latest max number of errors. All the oldest errors that were not read out will be dropped. In that case, the read to the corresponding overflow sysfs will return 1, otherwise, return 0.
+Example: ``overflow_core_ce`` to report the overflow status of Core CE error type.
+
+The format of the error is depended on the error type.
+
+1) For Core/Memory/PCIe/Other CE/UE error types::
+
+The return 48-byte in hex format in table below:
+
+ ======= ============= =========== ==========================================

Why not just put this in the driver itself to be generated automatically
instead of living in a file that will never be noticed if anything ever
changes?

I'm not sure what you mean by "to be generated automatically" but
information can be documented in the driver code itself and in the
Documentation/ABI entries.
Will drop this file and move them to both the driver code and to the
Documentaion/ABI entries in next version.

Usage Notes
-----------
SMpro errmon driver creates the sysfs files for each error type.
-Example: ``error_core_ce`` to get Core CE error type.
+See :ref:`smpro_sysfs` for the list of errors and the corresponding
+sysfs files.
-* If the error is absented, the sysfs file returns empty.
-* If the errors are presented, one each read to the sysfs, the oldest error will be returned and clear, the next read will be returned with the next error until all the errors are read out.
+* If there is no errors, the sysfs file is empty.
+* Otherwise, when errors occur, the oldest error
+ will be returned on sysfs file reading and cleared. The next read will
+ return the next error until all the errors are read out.
-For each host error type, SMpro keeps a latest max number of errors. All the oldest errors that were not read out will be dropped. In that case, the read to the corresponding overflow sysfs will return 1, otherwise, return 0.

This commit adds driver support for accessing various information
reported by Ampere's SMpro co-processor such as Boot Progress and
other miscellaneous data.
Signed-off-by: Quan Nguyen <quan@os.amperecomputing.com>
---
Changes in v9:
+ Update SPDX licence [Greg]
+ Use ATTRIBUTE_GROUPS() [Greg]
+ Use dev_groups instead of sysfs_create_group() to avoid
racing issue with user space [Greg]
+ Refactor code to avoid clever encoding issue [Quan]
Changes in v8:
+ Update wording for SMPRO_MISC in Kconfig file [Quan]
+ Switch to use sysfs_emit() [Quan]
Changes in v7:
+ Fix wrong return type of *_show/store()
functions [kernel robot test]
+ Adjust patch order to remove dependence with
smpro-mfd [Lee Jones]
Changes in v6:
+ First introduced in v6 [Quan]

Again, please put the Documentation/ABI/ entries in this commit so that
we can verify they are all correct. Putting them at the end of the
series makes it pretty impossible to review. Would you want to have to
match them all up the way you sent them?

+Kernel driver Ampere(R) Altra(R) SMpro miscellaneous
+====================================================
+
+Supported chips:
+
+ * Ampere(R) Altra(R)
+
+ Prefix: 'smpro'
+
+ Reference: Altra SoC BMC Interface Specification
+
+Author: Thu Nguyen <thu@os.amperecomputing.com>
+
+Description
+-----------
+
+This driver support the monitoring and configuration of various miscellaneous
+data provided by Ampere(R) Altra(R) SMpro processor.
+At this time, these include:
+
+ * Reading Boot Progress information
+ * Configuring SoC Power Limit
+
+Sysfs entries
+-------------
+
+1) Boot progress
+
+SMpro misc driver creates the sysfs files ``boot_progress``.
+The format of ``boot_progress`` file is as below::
+
+<boot stage><boot status><boot progress>
+
+Where:
+
+* Boot stage::
+
+ 0: SMpro firmware booting.
+ 1: PMpro firmware booting.
+ 2: ATF BL1 firmware booting.
+ 3: DDR initialization.
+ 4: DDR training report status.
+ 5: ATF BL2 firmware booting.
+ 6: ATF BL31 firmware booting.
+ 7: ATF BL32 firmware booting.
+ 8: UEFI firmware booting.
+ 9: OS booting.
+
+* Boot status::
+
+ 0: Not started.
+ 1: Started.
+ 2: Complete without error.
+ 3: Failure.
+
+* boot progress: 32 bits boot progress code
+
+The sysfs ``boot_progress`` only reports the boot state when the host is booting.
+If the host is already booted, it returns latest state.
+
+Example::
+
+ #cat boot_progress
+ 0102808454A8
+
+2) SoC Power Limit
+
+SMpro misc driver creates the sysfs file ``soc_power_limit`` to get/set the SoC Power Limit.
+
+Reading this sysfs return the current setting of SoC Power Limit (W) in decimal string.
+Writing the desired value in decimal string to set the SoC Power Limit in Watt (W).
+The range of SoC Power Limit is 90-500(W) and will be ignored if out of range.
+
+Example::
+
+ #cat soc_power_limit
+ 90
+ #echo 95 > soc_power_limit
+ #cat soc_power_limit
+ 95

Why is this file needed at all if you have the correct
Documentation/ABI/ entries instead?

Adds device tree bindings for SMPro MFD driver found on the Mt.Jade
hardware reference platform with Ampere's Altra Processor family.
The SMpro co-processor on Ampere Altra processor family is to monitor
and report various data included hwmon-related info, RAS errors, and
other miscellaneous information.
