• bool "ECI support"
• help

•  ECI (Enhancement Control Interface) accessory support
  

•  The Enhancement Control Interface functionality
  

•  ECI is better known as Multimedia Headset for Nokia phones.
  

•  If headset has many buttons, like play, vol+, vol- etc. then
  

•  it is propably ECI accessory.
  

•  Among several buttons ECI accessory contains memory for storing
  

•  several parameters.
  

•  Enable ECI support in terminal so that ECI input driver is able
  

•  to communicate with ECI accessory

•  Selects ECI driver debug messaging.
  

•  Say "yes" to enable debug messaging (like dev_dbg and pr_debug),
  

•  sysfs, and debugfs support in ECI controller.

+config ECI_BUS

• tristate "ECI bus controller driver"
• select INPUT_ECI

'select' INPUT_ECI when INPUT and/or INPUT_MISC are not enabled causes this kconfig warning:

warning: (ECI_BUS && ECI) selects INPUT_ECI which has unmet direct dependencies (!S390 && INPUT && INPUT_MISC)

• help

•  This selects a driver for the ECI bus controller
  

•  ECI bus controller is kind of bridge between host CPU I2C and
  

•  ECI accessory ECI communication.
  

•  Say 'y' here to statically link this module into the kernel or 'm'
  

•  to build it as a dynamically loadable module. The module will be
  

•  called ecibus.ko
