13 | Description | |
14 | ----------- | |
15 | ||
16 | LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter. | |
17 | ||
18 | ||
19 | Usage Notes | |
20 | ----------- | |
21 | ||
22 | This driver does not probe for PMBus devices. You will have to instantiate | |
23 | devices explicitly. | |
24 | ||
25 | Example: the following commands will load the driver for an LTC3815 | |
26 | at address 0x20 on I2C bus #1: | |
27 | ||
28 | # modprobe ltc3815 | |
29 | # echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | |
