ColorfulRhino a6b5ea7950 rk3588: Introduce current kernel branch 
Since the `edge` kernel branch often uses RC kernels, introduce a more stable `current` branch.
This branch should not be RC kernels and it also should move to an LTS kernel once released.

Subject: phy: rockchip: add usbdp combo phy driver
This adds a new USBDP combo PHY with Samsung IP block driver.
The driver get lane mux and mapping info in 2 ways, supporting
DisplayPort alternate mode or parsing from DT. When parsing from DT,
the property "rockchip,dp-lane-mux" provide the DP mux and mapping
info. This is needed when the PHY is not used with TypeC Alt-Mode.
For example if the USB3 interface of the PHY is connected to a USB
Type A connector and the DP interface is connected to a DisplayPort
connector.
When do DP link training, need to set lane number, link rate, swing,
and pre-emphasis via PHY configure interface.

The USBDP Phy is used by RK3588 to handle the Dual-Role USB3
controllers. The Phy also supports Displayport Alt-Mode, but
the necessary DRM driver has not yet been merged.

Subject: usb: typec: tcpm: avoid graph warning
When using a devicetree as described in commit d56de8c9a17d ("usb:
typec: tcpm: try to get role switch from tcpc fwnode"), the kernel
will print an error when probing the TCPM driver, which looks
similar to this:
OF: graph: no port node found in /i2c@feac0000/usb-typec@22
This is a false positive, since the code first tries to find a ports
node for the device and only then checks the fwnode. Fix this by
swapping the order.
Note, that this will now generate a error message for devicetrees with
a role-switch ports node directly in the TCPM node instead of in the
connectors sub-node, before falling back to the legacy behaviour. These
devicetrees generate warnings when being checked against the bindings,
and should be fixed.
Fixes: d56de8c9a17d ("usb: typec: tcpm: try to get role switch from tcpc fwnode")
