ON Semiconductor USB Type-C and display port 10Gbps Linear Re-Driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Must be "onnn,redriver".
|
||
|
|
- reg: I2C address on the selected bus.
|
||
|
|
- extcon: phandles to external connector devices. The first phandle
|
||
|
|
should point to the external connector which provides
|
||
|
|
both "USB" cable events and "USB-HOST" cable events.
|
||
|
|
An optional second phandle may be specified for DP
|
||
|
|
lane events.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- eq: Equalization value of re-driver channel A/B/C/D, 8 bit.
|
||
|
|
eq[0] - eq[3]: Channel A-D parameter for USB.
|
||
|
|
eq[4] - eq[7]: Channel A-D parameter for DP.
|
||
|
|
- flat-gain: Flat gain control value of re-driver channel A/B/C/D, 8 bit.
|
||
|
|
flat_gain[0] - flat_gain[3]: Channel A-D parameter for USB.
|
||
|
|
flat_gain[4] - flat_gain[7]: Channel A-D parameter for DP.
|
||
|
|
- output-comp: Output compression value of re-driver channel A/B/C/D,
|
||
|
|
8 bit.
|
||
|
|
output_comp[0] - output_comp[3]: Channel A-D parameter for USB.
|
||
|
|
output_comp[4] - output_comp[7]: Channel A-D parameter for DP.
|
||
|
|
- loss-match: Loss profile matching control value of re-driver channel
|
||
|
|
A/B/C/D, 8 bit.
|
||
|
|
loss_match[0] - loss_match[3]: Channel A-D parameter for USB.
|
||
|
|
loss_match[4] - loss_match[7]: Channel A-D parameter for DP.
