2023-07-17phy: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-05-19phy: qcom-qmp-combo: Introduce drm_bridgeBjorn Andersson
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.

2023-05-19phy: qcom-qmp-combo: Introduce orientation switchingBjorn Andersson
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.

However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Add the SM8550 both g4 and g3 configurations. In addition, there is a new "lane shared" table that needs to be configured for g4, along with the No-CSR list of resets. The no-CSR allows resetting the PHY without actually dropping the PHY configuration. The no-CSR needs to be deasserted only after the PHY has been configured and the PLL has stabilized.
