^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		From ISL29018 Data Sheet (FN6619.4, Oct 8, 2012) regarding the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		infrared suppression:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		Scheme 0, makes full n (4, 8, 12, 16) bits (unsigned) proximity
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		detection. The range of Scheme 0 proximity count is from 0 to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		2^n. Logic 1 of this bit, Scheme 1, makes n-1 (3, 7, 11, 15)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		bits (2's complementary) proximity_less_ambient detection. The
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		range of Scheme 1 proximity count is from -2^(n-1) to 2^(n-1).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		The sign bit is extended for resolutions less than 16. While
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		Scheme 0 has wider dynamic range, Scheme 1 proximity detection
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		is less affected by the ambient IR noise variation.
