Kernel driver pm6764tr

======================



Supported chips:



  * ST PM6764TR



    Prefix: 'pm6764tr'

Description:

------------



This driver supports the STMicroelectronics PM6764TR chip. The PM6764TR is a high

performance digital controller designed to power Intel’s VR12.5 processors and memories.



The device utilizes digital technology to implement all control and power management

functions to provide maximum flexibility and performance. The NVM is embedded to store

custom configurations. The PM6764TR device features up to 4-phase programmable operation.



The PM6764TR supports power state transitions featuring VFDE, and programmable DPM

maintaining the best efficiency over all loading conditions without compromising transient

response. The device assures fast and independent protection against load overcurrent,

under/overvoltage and feedback disconnections.
