Subject: [PATCH v6 0/2] hwmon: Add StarFive JH71X0 temperature sensor

This adds a driver for the temperature sensor on the JH7100 and JH7110,
RISC-V SoCs by StarFive Technology Co. Ltd.. The JH7100 is used on the
BeagleV Starlight board and StarFive VisionFive board. The JH7110 is
used on the StarFive VisionFive 2 board.

v6:
* Replace SOC_STARFIVE with ARCH_STARFIVE.

v5:
* Drop the "interrupts" property in dt-bindings.
* Reword the commit message of patch 2.
* Use continuous mode instead of single mode and drop the interrupt
  related code used in the single mode.
* Add the missing "default:" statements in the driver.
* Change the device name to "sfctemp" which avoids a warning when startup.

v4:
* Change the node name from "tmon" to "temperature-sensor" in dt-binding
  example, which is more generic.
* Add support for StarFive JH7110 SoC besides JH7100.
* Add clock and reset support in the dt-bindings and driver.
* Add the missing headers in patch 2.
* Use devm_platform_ioremap_resource() to remap instead of
  platform_get_resource() and devm_ioremap_resource().
* Use dev_err_probe() instead of dev_err().
* Add Signed-off-by tag for Hal Feng. Add Co-developed-by tag for
  Samin Guo in patch 2.

v3:
* Handle timeouts from wait_for_completion_interruptible_timeout
  properly.

v2:
* Fix checkpatch.pl --strict warnings
  - Add myself to MAINTAINERS
  - Fix multiline comments
  - Use proper case and whitespace for #defines
  - Add comment to sfctemp::lock mutex.
* Remaining comments by Guenter Roeck
  - Add Documentation/hwmon/sfctemp.rst
  - Use devm_add_action() and devm_hwmon_device_register_with_info()
    instead of a driver .remove function.
  - Don't do test conversion at probe time.
  - #include <linux/io.h>
  - Remove unused #defines
  - Use int return variable in sfctemp_convert().
* Add Samin's Signed-off-by to patch 2/2
