retimer芯片调式总结

1，主备状态是否ok。

 看里面的0-3工作在Master(master Active), 4-7 工作在Master(wait master)，主控0-3，备控4-7.

current postion说明：

typedef enum
{
    VEGA_HMUX_SWITCH_TO_MASTER = 0,
    VEGA_HMUX_SWITCH_TO_SLAVE = 1,
    VEGA_HMUX_SWITCH_TO_PATTERN = 2,
    VEGA_HMUX_SWITCH_TO_SM，
    VEGA_HMUX_SWITCH_TO_MASTER_FORCE，
    VEGA_HMUX_SWITCH_TO_SLAVE_FORCE，
    VEGA_HMUX_SWITCH_TO_PATTERN_FORCE，
}hmux_switch;

FSM_state说明：

2，line测和host测对应关系：

3，单主控和双主控的区别：
