My customer would like to fine tune EQ value via I2c, so could you advise how to do? currently their eye diagram is not good.
They set tusb544 to "4-lane_dp" or "2-lanes_dp+usb3.1" depending on attached dp dongle.
So which registers they need to adjust? Is UTX1EQ_SEL or URX1EQ_SEL ...tec
BTW, UTX1EQ_SEL or URX1EQ_SEL are included settings of "Downstream Facing Ports" and "Upstream Facing Port"?
which bits are DFP? which bits are UFP?
for "R" and "F", what value we should to set in i2c register?
