   4 Description:
   5                 This should return the calculated lux from the light sensor. If
   6                 it comes back in SI units, it should also include _input else it
   7                 should include _raw to signify it is not in SI units.

  12 Description:
  13                 Hardware dependent mode for an ALS device to calculate the value
  14                 in proximity mode. When this is enabled, then the device should
  15                 use a infrared sensor reading to remove infrared noise from the
  16                 proximity reading. If this is not enabled, the driver can still
  17                 do this calculation manually by reading the infrared sensor
  18                 value and doing the negation in sw.

  23 Description:
  24                 This property is supported by proximity sensors and should be
  25                 used to return the value of a reading by the sensor. If this
  26                 value is returned in SI units, it should also include _input
  27                 but if it is not, then it should include _raw.

  32 Description:
  33                 This property is supported by sensors that have an infrared
  34                 sensing mode. This value should be the output from a reading
  35                 and if expressed in SI units, should include _input. If this
  36                 value is not in SI units, then it should include _raw.

  54 Description:
  55                 This property gets/sets the table of coefficients
  56                 used in calculating illuminance in lux.

  62 KernelVersion:  3.6.0
  63 Contact:        [email protected]
  64 Description:
  65                 This property is supported by sensors that have a RGBC
  66                 sensing mode. This value should be the output from a reading
  67                 and if expressed in SI units, should include _input. If this
  68                 value is not in SI units (irradiance, uW/mm^2), then it should
  69                 include _raw.

  74 Description:
  75                 This should return the correlated color temperature from the
  76                 light sensor. If it comes back in SI units, it should also
  77                 include _input else it should include _raw to signify it is not
