403 Description
404 -----------
405
406 This driver supports the Renesas ISL68137 and
407 digital multiphase voltage regulators (raa_dmp
408 output 7-phase configurable PWM controller wit
409 generation devices are grouped into 4 distinct
410 single-rail devices, '2rail' for dual-rail dev
411 and 'hv' for high voltage single-rail devices.
412 for more information.
413
414 Usage Notes
415 -----------
416
417 This driver does not probe for PMBus devices.
418 devices explicitly.
419
420 The ISL68137 AVS operation mode must be enable
421
422 Beyond the normal sysfs pmbus attributes, the
423 for the ISL68137.
424
425 For 2nd generation Renesas digital multiphase
426 normal sysfs pmbus attributes are supported.
