1Kernel driver max16064 2====================== 3 4Supported chips: 5 6 * Maxim MAX16064 7 8 Prefix: 'max16064' 9 10 Addresses scanned: - 11 12 Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX16064.pdf 13 14Author: Guenter Roeck <linux@roeck-us.net> 15 16 17Description 18----------- 19 20This driver supports hardware monitoring for Maxim MAX16064 Quad Power-Supply 21Controller with Active-Voltage Output Control and PMBus Interface. 22 23The driver is a client driver to the core PMBus driver. 24Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 25 26 27Usage Notes 28----------- 29 30This driver does not auto-detect devices. You will have to instantiate the 31devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for 32details. 33 34 35Platform data support 36--------------------- 37 38The driver supports standard PMBus driver platform data. 39 40 41Sysfs entries 42------------- 43 44The following attributes are supported. Limits are read-write; all other 45attributes are read-only. 46 47======================= ======================================================== 48in[1-4]_label "vout[1-4]" 49in[1-4]_input Measured voltage.
