+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.
