Enabling this will cause the driver to read back the values written
|
|
to the chip's output register in order to detect errors.

This is slower but useful when debugging chips and/or busses.

For each DS28E17 detected, a new I2C adapter is created within the

kernel. I2C devices on that bus can be configured to be used by the
|
|
kernel and userspace tools as on any other "native" I2C bus.
|
|

This driver is also available as a module. If so, the module
|
|
will be called w1_ds28e17.
