hwmon: axiado-pwm-fan: Add missing documentation and MAINTAINERS entries

[PATCH] hwmon: axiado-pwm-fan: Add missing documentation and MAINTAINERS entries

Posted by Petar Stepanovic 1 day, 2 hours ago

The axiado-pwm-fan entry was added to the hwmon documentation index, but
the corresponding Documentation/hwmon/axiado-pwm-fan.rst file is missing.

The MAINTAINERS entry also only lists the devicetree binding and is missing
entries for the hwmon documentation and driver.

Add the missing documentation file and MAINTAINERS entries.

Fixes: 2d52742f408f ("hwmon: add Axiado AX3000 and AX3005 PWM fan controller driver")
Reported-by: kernel test robot <lkp@intel.com>

This patch adds the missing Axiado PWM fan documentation file and updates
the MAINTAINERS entry to include the documentation and driver source
files.

+Description
+-----------
+
+The Axiado AX3000 and AX3005 PWM fan controllers measure the rotational
+speed of one fan using a hardware tachometer block. Fan speed is controlled
+through a PWM signal supplied by an external PWM controller.
+
+The number of tachometer pulses generated per fan revolution is configured
+through the ``pulses-per-revolution`` devicetree property. If the property
+is not specified, the driver uses two pulses per revolution.
+
+Sysfs attributes
+----------------
+
+The driver provides the following standard hwmon attributes:
+
+=============== ====== =====================================================
+fan1_input      RO     Fan speed in revolutions per minute (RPM).
+
+pwm1            RW     Relative PWM control value from 0 to 255. A value of
+                       255 selects the maximum PWM duty cycle.

Sorry for that. The patch did not apply due to conflicts, and I had to
apply manually using patch. Doing so I forgot to include the missing
entries.

I'll fold this patch into the original patch introducing the driver.

Thanks,
Guenter
