Grant Peltier <grant.peltier.jg@renesas.com> + +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. + +ISL68137 sysfs attributes
