Description¶
This driver supports the Renesas ISL68137 and all 2nd generation Renesas digital multiphase voltage regulators (raa_dmpvr2). The ISL68137 is a digital output 7-phase configurable PWM controller with an AVSBus interface. 2nd generation devices are grouped into 4 distinct configurations: '1rail' for single-rail devices, '2rail' for dual-rail devices, '3rail' for 3-rail devices, and 'hv' for high voltage single-rail devices. Consult the individual datasheets for more information.
Usage Notes¶
This driver does not probe for PMBus devices. You will have to instantiate devices explicitly.
The ISL68137 AVS operation mode must be enabled/disabled at runtime.
Beyond the normal sysfs pmbus attributes, the driver exposes a control attribute for the ISL68137.
For 2nd generation Renesas digital multiphase voltage regulators, only the normal sysfs pmbus attributes are supported.
