46 $ref: /schemas/types.yaml#/definitions/uint8-array
50 an array of swing register setting for DP tx lane0 PHY.
51 Registers 0~9 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0,
52 Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2,
53 Swing1_Pre2, Swing0_Pre3, they are for [Boost control] and
54 [Swing control] setting.
55 Registers 0~9, bit 3:0 is [Boost control], these bits control
56 post cursor manual, increase the [Boost control] to increase
58 Registers 0~9, bit 6:4 is [Swing control], these bits control
59 swing manual, increase [Swing control] setting to add Vp-p value
61 Registers 10~19 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0,
62 Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2,
63 Swing1_Pre2, Swing0_Pre3, they are for [R select control] and
64 [R Termination control] setting.
65 Registers 10~19, bit 4:0 is [R select control], these bits are
66 compensation manual, increase it can enhance IO driven strength
68 Registers 10~19, bit 5:6 is [R termination control], these bits
69 adjust 50ohm impedance of DP tx termination. 00:55 ohm,
70 01:50 ohm(default), 10:45 ohm, 11:40 ohm.
