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