The QMP combo PHY sits in an of_graph connected between the DisplayPort controller and a USB Type-C connector (or possibly a redriver). The TCPM needs to be able to convey the HPD signal to the DisplayPort controller, but no directly link is provided by DeviceTree so the signal needs to "pass through" the QMP combo phy. Handle this by introducing a drm_bridge which upon initialization finds the next bridge (i.e. the usb-c-connector) and chain this together. This way HPD changes in the connector will propagate to the DisplayPort driver. The connector bridge is resolved lazily, as the TCPM is expected to be able to resolve the typec mux and switch at probe time, so the QMP combo phy will probe before the TCPM. Acked-by:

The data lanes of the QMP PHY is swapped in order to handle changing orientation of the USB Type-C cable. Register a typec_switch device to allow a TCPM to configure the orientation. The newly introduced orientation variable is adjusted based on the request, and the initialized components are brought down and up again. To keep track of what parts needs to be cycled new variables to keep track of the individual init_count is introduced. Both the USB and the DisplayPort altmode signals are properly switched. For DisplayPort the controller will after the TCPM having established orientation power on the PHY, so this is not done implicitly, but for USB the PHY typically is kept initialized across the switch, and must therefore then be reinitialized. This is based on initial work by Wesley Cheng. Link: https://lore.kernel.org/r/20201009082843.28503-3-wcheng@codeaurora.org/Reviewed-by:

In multiple places throughout the driver code has been written in prepration for handling of orientation switching. Introduce a typec_orientation in qmp_combo and fill out the various "placeholders" with the associated logic. By initializing the orientation to "normal" this change has no functional impact, but reduces the size of the upcoming introduction of dynamic orientation switching. Reviewed-by:

The phy core ensures mutual exclusion across the ops for a given phy, but the upcoming introduction of USB Type-C orientation switching might race with the DisplayPort phy operations. So extend the mutual exclusion to cover the remaining ops as well, to avoid concurrent reconfiguration of the hardware. Reported-by:

With the upcoming introduction of USB Type-C orientation switching the region of mutual exclusion needs to be extended to cover both the common init/exit as well as the individual functions. So move the phy_mutex one step up the stack. Reviewed-by:

For NXP platform design, the PHY can't know VBUS well, it causes the FSM in controller seeing the disconnection at L1 use case. With .set_mode API introduced, the controller driver could force PHY seeing B Session VALID when it is at the device mode (VBUS is there), and keep FSM working well. Signed-off-by:

Very limited parts may fail to work on full speed mode (both host and device modes) for USB3 port due to higher threshold in full speed receiver of USB2.0 PHY. One example failure symptom is, the enumeration is failed when connecting full speed USB mouse to USB3 port, especially under high temperature. The workaround is to configure threshold voltage value of single ended receiver by setting USB2.0 PHY register AFE_RX_REG5[2:0] to 3'b101. Signed-off-by:

For USB2 L1 use cases, some hosts may start transferring less than 20us after End of Resume, it causes the host seeing corrupt packet from the device side. The reason is the delay time between PHY powers up and txvalid is 20us. To fix it, we change the delay value as 0us. Signed-off-by:

Note that the binding now does not describe every register subregion and instead the driver holds the corresponding offsets.

'qcom,msm8996-qmp-usb3-phy.yaml' defines bindings for several PHYs which predate USB -> USB+DP migration. Since SM6115 and QCM2290 nodes for USB QMP phy are being added to dtsi files by followup patches, move these bindings instead to the newer style 'qcom,sc8280xp-qmp-usb3-uni-phy.yaml' file. Since no device trees use these bindings presently, so we have no ABI breakages with this patch. Signed-off-by:
