Qualcomm Technologies, Inc. QPNP PD PHY - USB Power Delivery Physical layer
|
|
|
|
Required properties:
|
|
- compatible: Must be "qcom,qpnp-pdphy"
|
|
- reg: The base address for this peripheral
|
|
- vdd-pdphy-supply: phandle to the VDD supply regulator node
|
|
- interrupts: Specifies the interrupt associated with the peripheral.
|
|
- interrupt-names: Specifies the interrupt names for the peripheral. Every
|
|
available interrupt needs to have an associated name
|
|
with it to indentify its purpose.
|
|
|
|
The following interrupts are required:
|
|
|
|
0: sig-tx
|
|
Triggers when a signal (HardReset or CableReset)
|
|
has been sent.
|
|
1: sig-rx
|
|
Triggers when a signal has been received.
|
|
2: msg-tx
|
|
Triggers when a message has been sent and the
|
|
related GoodCRC has been received.
|
|
3: msg-rx
|
|
Triggers when a message has been received and
|
|
the related GoodCRC was sent successfully.
|
|
4: msg-tx-failed
|
|
Triggers when a message failed all its
|
|
transmission attempts, either due to a non-idle
|
|
bus or missing GoodCRC reply.
|
|
5: msg-tx-discarded
|
|
Triggers when a message is received while a
|
|
transmission request was in place. The request
|
|
itself is discarded.
|
|
6: msg-rx-discarded
|
|
Triggers when a message was received but had to
|
|
be discarded due to the RX buffer still in use
|
|
by SW.
|
|
|
|
Optional properties:
|
|
- vbus-supply: Regulator that enables VBUS source output
|
|
- vconn-supply: Regulator that enables VCONN source output. This will
|
|
be supplied on the USB CC line that is not used for
|
|
communication when Ra resistance is detected.
|
|
- qcom,default-sink-caps: List of 32-bit values representing the nominal sink
|
|
capabilities in voltage (millivolts) and current
|
|
(milliamps) pairs.
|
|
- qcom,no-usb3-dp-concurrency: If present, usb3 and dp concurrency is not supported.
|
|
- qcom,pd-20-source-only: If present, only PD2.0 is supported as source.
|
|
|
|
Example:
|
|
qcom,qpnp-pdphy@1700 {
|
|
compatible = "qcom,qpnp-pdphy";
