UCSI already conveys the information about a port's connection status, whether it is operating in UFP or DFP mode, and whether the partner supports USB data or not. This information can be used to notify a dual-role controller to start up its host or peripheral mode accordingly. Add optional support for this by querying each port's fwnode to look for an associated USB role switch device. If present, call usb_role_switch_set() with the determined data role upon Connect Change or Connector Partner Change updates. Reviewed-by:

Link Power Management (LPM) on STM32MP15 OTG HS encounters instabilities with some Host controllers. OTG core fails to exit L1 state in 200us: "dwc2 49000000.usb-otg: Failed to exit L1 sleep state in 200us." Then the device is still not enumerated. To avoid this issue, disable Link Power Management on STM32MP15 HS OTG. Acked-by:

When the core is in FS host mode, using the FS transceiver, and a Low-Speed device is connected, transceiver clock is 6Mhz. So, to support Low-Speed devices, enable support of FS/LS Low Power mode, so that the PHY supplies a 6 MHz clock during Low-Speed mode. Acked-by:

STM32MP15 ahbcfg register default value sets Burst length/type (HBSTLEN) to Single (32-bit accesses on AHB), which is not recommended, according to STM32MP157 Reference manual [1]. This patch sets Burst length/type (HBSTLEN) so that bus transactions target 16x32 bit accesses. This improves OTG controller performance.

Currently a tasklet is used to transmit input substream buffer data. However, tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. Deferring work to a workqueue and executing in process context should be fine considering the callback already does f_midi_do_transmit() under the transmit_lock and thus changes in semantics are ok regarding concurrency - tasklets being serialized against itself.

For some UDCs, the initialization sequence by udc_start() should not be repeated until it is properly cleaned up with udc_stop() and vise versa. We may run into some cleanup failure as seen with the DWC3 driver during the irq cleanup. This issue can occur when the user triggers soft-connect/soft-disconnect from the soft_connect sysfs. To avoid adding checks to every UDC driver, at the UDC framework, introduce a "started" state to track and prevent the UDC from repeating the udc_start() and udc_stop() if it had already started/stopped.

DWC USB3 DT node is supposed to be compliant with the Generic xHCI Controller schema, but with additional vendor-specific properties, the controller-specific reference clocks and PHYs. So let's convert the currently available legacy text-based DWC USB3 bindings to the DT schema and make sure the DWC USB3 nodes are also validated against the usb-xhci.yaml schema. Note 1. we have to discard the nodename restriction of being prefixed with "dwc3@" string, since in accordance with the usb-hcd.yaml schema USB nodes are supposed to be named as "^usb(@.*)". Note 2. The clock-related properties are marked as optional to match the DWC USB3 driver expectation and to improve the bindings mainainability so in case if there is a glue-node it would the responsible for the clocks initialization.

Currently the DT bindings of Generic xHCI Controllers are described by means of the legacy text file. Since such format is deprecated in favor of the DT schema, let's convert the Generic xHCI Controllers bindings file to the corresponding yaml files. There will be two of them: a DT schema for the xHCI controllers on a generic platform and a DT schema validating a generic xHCI controllers properties. The later will be used to validate the xHCI controllers, which aside from some vendor-specific features support the basic xHCI functionality. An xHCI-compatible DT node shall support the standard USB HCD properties and custom ones like: usb2-lpm-disable, usb3-lpm-capable, quirk-broken-port-ped and imod-interval-ns. In addition if a generic xHCI controller is being validated against the DT schema it is also supposed to be equipped with mandatory compatible string, single registers range, single interrupts source, and is supposed to optionally contain up to two reference clocks for the controller core and CSRs.

Even though the Generic PHY framework is the more preferable way of setting the USB PHY up, there are still many dts-files and DT bindings which rely on having the legacy "usb-phy" specified to attach particular USB PHYs to USB cores. Let's have the "usb-phy" property described in the generic USB HCD binding file so it would be validated against the nodes in which it's specified. Mark the property as deprecated to discourage the developers from using it. Reviewed-by:

The generic USB properties have been described in the legacy bindings text file: Documentation/devicetree/bindings/usb/generic.txt . Let's convert its content into the generic USB, USB HCD and USB DRD DT schemas. So the Generic USB schema will be applicable to all USB controllers, USB HCD - for the generic USB Host controllers and the USB DRD - for the USB Dual-role controllers. Note the USB DRD schema is supposed to work in conjunction with the USB peripheral/gadget and USB host controllers DT schemas. Reviewed-by:

There can be three distinctive types of the USB controllers: USB hosts, USB peripherals/gadgets and USB OTG, which can switch from one role to another. In order to have that hierarchy handled in the DT binding files, we need to collect common properties in a common DT schema and specific properties in dedicated schemas. Seeing the usb-hcd.yaml DT schema is dedicated for the USB host controllers only, let's move some common properties from there into the usb.yaml schema. So the later would be available to evaluate all currently supported types of the USB controllers. While at it add an explicit "additionalProperties: true" into the usb-hcd.yaml as setting the additionalProperties/unevaluateProperties properties is going to be get mandatory soon. Reviewed-by:
