I2C chip IDs need to reflect chip names, not chip functionality.

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.
