17 | Description | |
18 | ----------- | |
19 | ||
20 | LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter. | |
21 | ||
22 | ||
23 | Usage Notes | |
24 | ----------- | |
25 | ||
26 | This driver does not probe for PMBus devices. You will have to instantiate | |
27 | devices explicitly. | |
28 | ||
29 | Example: the following commands will load the driver for an LTC3815 | |
1f234ff1 | 30 | at address 0x20 on I2C bus #1:: |
8d28cd1b | 31 | |
1f234ff1 MCC |
32 | # modprobe ltc3815 |
33 | # echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | |
