	There is no point in implementing a detect callback for the LTC4215 and LTC4245, as these devices can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callbacks. This shrinks the binary module sizes by 36% and 46%, respectively.

2009-09-23	hwmon: (ltc4215) Clear faults at startup	Ira W. Snyder
	When power is applied to the ltc4215 chip it sometimes reports spurious faults. The faults are not yet exposed via sysfs, however it may be useful for userspace to read the fault register directly with the i2cget command. Clear the fault register when the driver is installed so userspace doesn't have to worry about spurious fault indications. Signed-off-by: Ira W.

2009-04-01	hwmon: Add LTC4215 driver	Ira Snyder
	Add Linux support for the Linear Technology LTC4215 Hot Swap controller I2C monitoring interface. I have tested the driver with my board, and it appears to work fine. With the power supplies disabled, it reads 11.93V input, 1.93V output, no current and no power. With the supplies enabled, it reads 11.93V input, 11.98V output, no current, no power. I'm not drawing any current at the moment, so this is reasonable. The value in the sense register never reads anything except 0, so I expect to get zero from the current and power calculations. I didn't attempt to support changing any of the chip's settings or enabling the FET. I'm not sure even how to do that and still fit within the hwmon framework. :) Signed-off-by: Ira W.
