Please see Documentation/i2c/instantiating-devices for -details. - -Module parameters ------------------ - -If your board has a BIOS that initializes the MAX6650/6651 correctly, you can -simply load your module without parameters. It won't touch the configuration -registers then. If your board BIOS doesn't initialize the chip, or you want -different settings, you can set the following parameters: - -voltage_12V: 5=5V fan, 12=12V fan, 0=don't change -prescaler: Possible values are 1,2,4,8,16, or 0 for don't change -clock: The clock frequency in Hz of the chip the driver should assume [254000] - -Please have a look at the MAX6650/6651 data sheet and make sure that you fully -understand the meaning of these parameters before you attempt to change them. - |
