  1. Kernel driver ltc3815
  2. =====================
  3. Supported chips:
  4. * Linear Technology LTC3815
  5. Prefix: 'ltc3815'
  6. Addresses scanned: -
  7. Datasheet: http://www.linear.com/product/ltc3815
  8. Author: Guenter Roeck <linux@roeck-us.net>
  9. Description
  10. -----------
  11. LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter.
  12. Usage Notes
  13. -----------
  14. This driver does not probe for PMBus devices. You will have to instantiate
  15. devices explicitly.
  16. Example: the following commands will load the driver for an LTC3815
  17. at address 0x20 on I2C bus #1::
  18. # modprobe ltc3815
  19. # echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
