Subject: [PATCH v2 2/4] hwmon: Add Aspeed AST2600 support
Date: Wed, 13 Jan 2021 07:08:46 +0000	[thread overview]
Message-ID: <20210113070850.1184506-3-troy_lee@aspeedtech.com> (raw)
In-Reply-To: <20210113070850.1184506-1-troy_lee@aspeedtech.com>

Updating index.rst and adding aspeed2600-pwm-tachometer.rst to address
the driver.

Changes since v1:
- rename to aspeed2600-pwm-tachometer.rst
- add license identifier

+Description:
+------------
+This driver implements support for ASPEED AST2600 PWM and Fan Tacho
+controller. The PWM controller supports upto 16 PWM outputs. The Fan tacho
+controller supports up to 16 tachometer inputs.
+
+The driver provides the following sensor accesses in sysfs:
+
+=============== ======= =====================================================
+fanX_input	ro	provide current fan rotation value in RPM as reported
+			by the fan to the device.
+
+pwmX		rw	get or set PWM fan control value. This is an integer
+			value between 0(off) and 255(full speed).
