+ - Intel VR13 DC-DC converter specifications.
+ - Intel SVID protocol.
+
Used for DDR3/DDR4 Memory power regulation for Intel VR13 and
IMVP8 based systems
to instantiate devices explicitly.
Example: the following commands will load the driver for an PXE1610
-at address 0x70 on I2C bus #4:
+at address 0x70 on I2C bus #4::
-# modprobe pxe1610
-# echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
+ # modprobe pxe1610
+ # echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device
It can also be instantiated by declaring in device tree
