+Kernel driver adm1266
+=====================
+
+Supported chips:
+  * Analog Devices ADM1266
+    Prefix: 'adm1266'
+    Datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/ADM1266.pdf
+
+Author: Alexandru Tachici <alexandru.tachici@analog.com>
+
+
+Description
+-----------
+
+This driver supports hardware monitoring for Analog Devices ADM1266 sequencer.
+
+ADM1266 is a sequencer that features voltage readback from 17 channels via an
+integrated 12 bit SAR ADC, accessed using a PMBus interface.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus for details on PMBus client drivers.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write, history reset
+attributes are write-only, all other attributes are read-only.
+
+inX_label		"voutx"
+inX_input		Measured voltage.
+inX_min			Minimum Voltage.
+inX_max			Maximum voltage.
+inX_min_alarm		Voltage low alarm.
+inX_max_alarm		Voltage high alarm.
