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