0035 Description
0036 -----------
0037
0038 This driver supports the MAX16508 VR13 Dual-Output Voltage Regulator
0039 as well as the MAX16601 VR13.HC Dual-Output Voltage Regulator chipsets.
0040
0041 The driver is a client driver to the core PMBus driver.
0042 Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
0043
0044
0045 Usage Notes
0046 -----------
0047
0048 This driver does not auto-detect devices. You will have to instantiate the
0049 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
0050 details.
0051
0052
0053 Platform data support
0054 ---------------------
0055
0056 The driver supports standard PMBus driver platform data.
