hwmon: (max16064) Add driver documentation 



MAX16064 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 MAX16064 Quad Power-Supply

Controller with Active-Voltage Output Control and 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.



in[1-4]_label		"vout[1-4]"

in[1-4]_input		Measured voltage. From READ_VOUT register.

in[1-4]_min		Minumum Voltage. From VOUT_UV_WARN_LIMIT register.

in[1-4]_max		Maximum voltage. From VOUT_OV_WARN_LIMIT register.

in[1-4]_lcrit		Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.

in[1-4]_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.

in[1-4]_min_alarm	Voltage low alarm. From VOLTAGE_UV_WARNING status.

in[1-4]_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.

in[1-4]_lcrit_alarm	Voltage critical low alarm. From VOLTAGE_UV_FAULT status.

in[1-4]_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_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.
