The OF core adds an alias based on the OF device ID table, which is enough to have the driver autoloaded. The legacy MODULE_ALIAS macro was relevant to a pre-OF board files which manually created platform devices, this is irrelevant to the modern ARM kernels since devices are created by the OF core. Remove the unnecessary macro in order to keep the driver's code cleaner.

The PHY hardware needs the delay of 2ms after power up, otherwise initial interrupt may be lost if USB controller is accessed before PHY is settled down. Previously this issue was masked by implicit delays, but now it pops up after squashing the older ehci-tegra driver into the ChipIdea driver.

Mayank Rana authored
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.

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.

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.

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.
