Git-commit: 1ccd5417dbfa77afb476b95c85fe2e43ada2bc0a
Patch-mainline: v5.5-rc1
References: bsc#1152472
LT-tunable PHY Repeaters can operate in two different modes: transparent
(default) and non-transparent. The value 0x55 specifies the transparent
mode, and 0xaa represents the non-transparent; this commit adds these
two values as definitions.
