[PATCH 2/4] hwmon: (max8688) Add driver documentation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



MAX8688 has its own driver, thus should have its own documentation instead of
being mentioned in the generic PMBus driver documentation.

+
+Description
+-----------
+
+This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply
+Controller/Monitor with PMBus Interface.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus for details on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+details.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported. Limits are read-write; all other
+attributes are read-only.
+
+in1_label		"vout1"
+in1_input		Measured voltage. From READ_VOUT register.
+in1_min			Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
+in1_max			Maximum voltage. From VOUT_OV_WARN_LIMIT register.
+in1_lcrit		Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
+in1_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
+in1_min_alarm		Voltage low alarm. From VOLTAGE_UV_WARNING status.
+in1_max_alarm		Voltage high alarm. From VOLTAGE_OV_WARNING status.
+in1_lcrit_alarm		Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
+in1_crit_alarm		Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
+
+curr1_label		"iout1"
+curr1_input		Measured current. From READ_IOUT register.
+curr1_max		Maximum current. From IOUT_OC_WARN_LIMIT register.
+curr1_crit		Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
+curr1_max_alarm		Current high alarm. From IOUT_OC_WARN_LIMIT register.
+curr1_crit_alarm	Current critical high alarm. From IOUT_OC_FAULT status.
+
+temp1_input		Measured temperature. From READ_TEMPERATURE_1 register.
+temp1_max		Maximum temperature. From OT_WARN_LIMIT register.
+temp1_crit		Critical high temperature. From OT_FAULT_LIMIT register.
+temp1_max_alarm		Chip temperature high alarm. Set by comparing
+			READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
+			status is set.
+temp1_crit_alarm	Chip temperature critical high alarm. Set by comparing
+			READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
+			status is set.
