I'm dropping the previous V1-V6 log because the text is getting too long
here's a link to the previous cover letter instead

Bootable tree
Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-23-05-07-pm8150b-tcpm-qcom-wrapper-typec-mux-bjorn
Please note patch#5 and patch#6 should be merged in tandem not separately.
V7:
- Adds R/B to "dt-bindings: phy: qcom,sc7180-qmp-usb3-dp-phy: Add input and output ports" - Krzysztof
- Fixes indicated, adds R/B to "dt-bindings: usb: Add Qualcomm PMIC Type-C" - Krzysztof
- Fixes indicated, adds R/B to "usb: typec: qcom: Add Qualcomm PMIC Type-C driver" - Guenter
- Fixes indicated, adds R/B to "usb: typec: qcom: Add Qualcomm PMIC Type-C driver" - Caleb
- Adds R/B to "arm64: dts: qcom: sm8250: Define ports for qmpphy orientation-switching" - Konrad
- Adds R/B to "arm64: dts: qcom: qrb5165-rb5: Switch on Type-C VBUS boost" - Konrad
- Fixes indicated, adds R/B to "arm64: dts: qcom: qrb5165-rb5: Switch on basic TCPM" - Jianhua, Konrad
- Connector ports/endpoints left inside of connector
Documentation/devicetree/bindings/connector/usb-connector.yaml - Jianhua
- dwc3_role_switch_in -> usb_1_dwc3_role_switch_in
qmpphy_typec_mux_in -> usb_1_qmpphy_typec_mux_in
Both ports/endpoints defined inside of pm8150b dtsi - Konrad
I modified the name of both so that the port/endpoint would be directly
adjacent to the containing node in the dtsi file for code locality/readbility - bod
- Fixes newline indicated "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM usb-role-switching for usb_1" - Jianhua, Konrad
- Fixes newline indicated "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM orientation-switch for usb_1_qmpphy" - Jianhua, Konrad
- connector
I have left the connector defintion and its ports/endpoints in the platform dts
The reason for this
a) Prior art e.g. arch/arm64/boot/dts/qcom/sc8280xp*
b) The connector is really a non-SoC/PMIC component its something that is defined
for your platform.
I'm open to further debate on this topic:
Link: https://imgflip.com/i/7kw6ck
- port@1 -> port@1 "arm64: dts: qcom: qrb5165-rb5: Switch on TCPM orientation-switch for usb_1_qmpphy" - Jianhua
- OF: graph: no port node found in /soc@0/spmi@c440000/pmic@2/typec@1500
I left this as-is since the DT model we want is to connect the connector directly to
the PHY for orientation or controller for data-role switching
I similarly didn't put this hack in place to remove the warning but "it would work"
&pm8150b_typec {
status = "okay";

+ port@0 {
+ reg = <0>;
+ };
+ };
+
- Fairphone4 / sm7225
pm7250b is a derivative of pm8150b I have the hardware but, haven't booted to test/debug on this hardware yet
- RB3 / sdm845
Caleb has a WIP patchset based on this series which is our next likely upstream candidate
Here's how I'm testing using an RB5/SM8250
A) Confirm device mode works in both orientations
- Boot to a Linux shell
- Run usb-ecm-up.sh [1]
- This provides usb0 on the device side @ 192.168.8.2
- Attach Type-C cable to host PC
- On host PC "sudo ifconfig usb0 192.168.8.1"
- Ping 192.168.8.2 confirming ping works
- Switch cable orientation
- On the PC side re-assign the ip address "sudo ifconfig usb0 192.168.8.1"
- Ping again confirming connectivity
B) Test automatic host-mode transition, orientation and SuperSpeed
- Remove cable from PC
- Attach a Type-C USB key
- Validate the orientation detection
cat /sys/class/typec/port0/orientation
normal
- Confirm the RB5 sees the USB key as a SuperSpeed device
- Remove USB key and physically invert it along the horizontal axis
- Re-insert the key
- Confirm the RB5 sees the USB key as a SuperSpeed device
- Validate the orientation detection
cat /sys/class/typec/port0/orientation
reverse
C) Test Type-C accessory automatic host-mode transition, orientation and SuperSpeed
- Remove USB key from RB5
- Attach a Type-C USB accessory
- Validate the orientation detection
cat /sys/class/typec/port0/orientation
normal
- Attach a SuperSpeed capable USB key to the Type-C accessory
- Confirm the RB5 sees the USB key as a SuperSpeed device
- Remove the USB key from the Type-C accessory
- Remove the Type-C accessory from the RB5
- Physically invert the Type-C accessory along the horizontal axis
- Re-insert the Type-C accessory
- Validate the orientation detection
cat /sys/class/typec/port0/orientation
reverse
- Re-insert the key
- Confirm the RB5 sees the USB key as a SuperSpeed device
D) Goto Test-A
- Confirming that automatic switch to device mode happens
- Repeat the above loop in ~ any order

The regulator code needs to know the location of the register to write to
to switch on/off. Right now we have a driver that does this, a yaml that
partially describes it and no dts that uses it.
Switching on the VBUS for sm8250 shows that we haven't documented reg as a
required property, do so now.

The VBUS driver needs to know the regulator-min-microamp and
regulator-max-microamp so they should both be marked as required.
regulator.yaml defines those two dependencies so include regulator.yaml.
We need to change from additionalProperties: false to
unevaluatedProperties: false.

orientation-switch it the standard declaration to inform the Type-C mux
layer that a remote-endpoint is capable of processing orientation change
messages.
Add as an optional since not all versions of the dp-phy currently support
the orientation-switch.

Add a ports declaration which is optional containing two port@
declarations.
port@0 to receive an orientation-switch message from the Type-C port or
redriver
port@1 to subsequently transmit the orientation-switch on once the PHY has
finished doing its orientation turn-around.
If ports is declared the input port port@0 is mandatory but the output
port@1 is optional.

This commit adds a QCOM PMIC TCPM driver with an initial pm8150b
block.
The driver is layered as follows:
qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates
access to the Type-C and PDPHY hardware blocks in one
place. This presents a single TCPM device to device to
the Linux TCPM layer.
qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and
processing power-delivery related calls from TCPM.
This hardware binding can be extended to
facilitate similar hardware in different PMICs.
qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C
related calls from TCPM. Similar to the pdphy this
layer can be extended to handle the specifics of
different Qualcomm PMIC Type-C port managers.
This code provides all of the same functionality as the existing
qcom typec driver plus power-delivery as well.
As a result commit 6c8cf3695176 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.
References code from Jonathan Marek, Jack Pham, Wesley Cheng, Hemant Kumar,
Guru Das Srinagesh and Ashay Jaiswal.

Type-C port management functionality lives inside of the PMIC block on
pm8150b.
The Type-C port management logic controls orientation detection, vbus/vconn
sense and to send/receive Type-C Power Domain messages.

Switch on VBUS for the Type-C port. We need to support a higher amperage
than the bootloader set 2 Amps.

Switch on TCPM for the RB5. Here we declare as a source only not a sink
since qrb5165 doesn't support powering exclusively from the type-c port.

Switch on usb-role-switching for usb_1 via TCPM. We need to declare
usb-role-switch in &usb_1 and associate with the remote-endpoint in TCPM
which provides the necessary signal.

Switch on USB orientation-switching for usb_1_qmp via TCPM. Detecting the
orientation switch is required to get the PHY to reset and bring-up the PHY
with the CC lines set to the appropriate lane.
