These two attributes are only used in the one driver. Whilst they are fairly general I'm not entirely happy committing to them at this stage. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

|
|
Description:
|
|
This attribute, if available, is used to enable the AC
|
|
excitation mode found on some converters. In ac excitation mode,
|
|
the polarity of the excitation voltage is reversed on
|
|
alternate cycles, to eliminate DC errors.

KernelVersion: 3.1.0

|
|
Description:
|
|
This attribute, if available, is used to close or open the
|
|
bridge power down switch found on some converters.
|
|
In bridge applications, such as strain gauges and load cells,
|
|
the bridge itself consumes the majority of the current in the
|
|
system. To minimize the current consumption of the system,
|
|
the bridge can be disconnected (when it is not being used
|
|
using the bridge_switch_en attribute.
