There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

Description:
|
|
From ISL29018 Data Sheet (FN6619.4, Oct 8, 2012) regarding the
|
|
infrared suppression:
|
|
|
|
Scheme 0, makes full n (4, 8, 12, 16) bits (unsigned) proximity
|
|
detection. The range of Scheme 0 proximity count is from 0 to
|
|
2^n. Logic 1 of this bit, Scheme 1, makes n-1 (3, 7, 11, 15)
|
|
bits (2's complementary) proximity_less_ambient detection. The
|
|
range of Scheme 1 proximity count is from -2^(n-1) to 2^(n-1).
|
|
The sign bit is extended for resolutions less than 16. While
|
|
Scheme 0 has wider dynamic range, Scheme 1 proximity detection
|
|
is less affected by the ambient IR noise variation.
