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