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.
- qcom,pps-disabled: If defined pps support will be disabled. Standard PD
communication will remain unaffected.
Example:
qcom,qpnp-pdphy@1700 {
compatible = "qcom,qpnp-pdphy";
reg = <0x1700 0x100>;
vdd-pdphy-supply = <&pm8998_l24>;
interrupts = <0x2 0x17 0x0 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x1 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x2 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x3 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x4 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x5 IRQ_TYPE_EDGE_RISING>,
<0x2 0x17 0x6 IRQ_TYPE_EDGE_RISING>;
interrupt-names = "sig-tx",
"sig-rx",
"msg-tx",
"msg-rx",
"msg-tx-failed",
"msg-tx-discarded",
"msg-rx-discarded";
qcom,default-sink-caps = <5000 3000>, /* 5V @ 3A */
<9000 3000>, /* 9V @ 3A */
<12000 2250>; /* 12V @ 2.25A */
};
