   51       an array of swing register setting for DP tx lane0 PHY.
   52       Registers 0~9 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0,
   53       Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2,
   54       Swing1_Pre2, Swing0_Pre3, they are for [Boost control] and
   55       [Swing control] setting.
   56       Registers 0~9, bit 3:0 is [Boost control], these bits control
   57       post cursor manual, increase the [Boost control] to increase
   58       Pre-emphasis value.
   59       Registers 0~9, bit 6:4 is [Swing control], these bits control
   60       swing manual, increase [Swing control] setting to add Vp-p value
   61       for each Swing, Pre.
   62       Registers 10~19 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0,
   63       Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2,
   64       Swing1_Pre2, Swing0_Pre3, they are for [R select control] and
   65       [R Termination control] setting.
   66       Registers 10~19, bit 4:0 is [R select control], these bits are
   67       compensation manual, increase it can enhance IO driven strength
   68       and Vp-p.
   69       Registers 10~19, bit 5:6 is [R termination control], these bits
   70       adjust 50ohm impedance of DP tx termination. 00:55 ohm,
   71       01:50 ohm(default), 10:45 ohm, 11:40 ohm.
