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. |
