…kernel/git/groeck/linux-staging

Pull hwmon updates from Guenter Roeck:
 "New drivers:

   - Driver for OneXPlayer mini AMD sensors

   - Ampere's Altra smpro-hwmon driver

  New chip and attribute support in existing drivers:

   - nct6775: Support for ASUS CROSSHAIR VIII/TUF/ProArt B550M

  Improvements:

   - Use devm_regulator_get_enable() where appropriate

   - Use sysfs_emit() instead of scnprintf()

   - Remove some useless #include <linux/hwmon-vid.h>

   - Include <linux/kstrtox.h> when appropriate

   - Use simple i2c probe

   - it87: Check for a valid chip before using force_id, and new new
     module parameter to ignore ACPI resource conflicts

   - jc42: Use regmap, and restore min/max/critical temperatures on
     resume

   - Add reporting power good and status to PMBus based regulators

  Last minute fixes:

   - emc2305: Fix probing of emc2301/2/3, and fix setting pwm values
     manually if THERMAL is enabled

  And various other minor fixes and improvements"

+
+One X Player devices from One Netbook provide fan readings and fan control

+Currently only supports AMD boards from the One X Player and AOK ZOE lineup.
+Intel boards could be supported if we could figure out the EC registers and

+Supported devices
+-----------------
+
+Currently the driver supports the following handhelds:
+
+ - AOK ZOE A1
+ - OneXPlayer AMD
+ - OneXPlayer mini AMD
+ - OneXPlayer mini AMD PRO

+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
+-----------
+The smpro-hwmon driver supports hardware monitoring for Ampere(R) Altra(R)
+SoCs based on the SMpro co-processor (SMpro).  The following sensor metrics
+are supported by the driver:
+
+  * temperature
+  * voltage
+  * current
+  * power
+
+The interface provides the registers to query the various sensors and
+their values which are then exported to userspace by this driver.
+
+Usage Notes
+-----------
+
+The driver creates at least two sysfs files for each sensor.
+
+* ``<sensor_type><idx>_label`` reports the sensor label.
+* ``<sensor_type><idx>_input`` returns the sensor value.
+
+The sysfs files are allocated in the SMpro rootfs folder, with one root
+directory for each 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:
