| * | | | USB: dwc3: clean up phy init error handlingJohan Hovold2023-04-201-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While there likely are no platforms out there that mix generic and legacy PHYs the driver should still be able to handle that, if only for consistency reasons. Add the missing calls to shutdown any legacy PHYs if generic PHY initialisation fails. Note that we continue to happily ignore potential errors from the legacy PHY callbacks...

| * | | | USB: dwc3: drop dead hibernation codeJohan Hovold2023-04-202-110/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hibernation code is broken and has never been enabled in mainline and should thus be dropped. Specifically, the scratch buffer DMA mapping would have been leaked on every suspend cycle since commit 51f5d49ad6f0 ("usb: dwc3: core: simplify suspend/resume operations") if this feature was ever enabled. The related error handling was also broken and could have resulted in attempts to unmap never mapped buffers, etc. This effectively revert commit 0ffcaf3798bf ("usb: dwc3: core: allocate scratch buffers").

This is because the ACPI interrupt handler destroys the CCI in ERAM after copying to system memory, and when _DSM is later called to perform a second copy, it retrieves a garbage value. Instead, the _DSM(read) method should only be called when necessary, i.e. for polling the state after reset and for retrieving the version. Other reads should not call _DSM and only peek into the RAM region. This adds a separate read operation for the Zenbook that syncs the ACPI mailbox only with polled commands.

Some digging in the kernel's history revealed no good reason why it needs to be defined in USB's top-level Kconfig file, and why the config for the USS720 parport driver should be the first in the list of USB port drivers, while all other configs for drivers in drivers/usb/misc are in the USB Miscellaneous driver configuration file. Most probably, it was simply considered a bit more special when the USB Miscellaneous driver configuration file (drivers/usb/misc/Config.in back then) was initially created, and this config simply survived to remain at the top-level USB Kconfig file with all further code/Kconfig transformations and additions later on. Users rarely notice this config being at this position, as CONFIG_PARPORT (Parallel port support) needs to be enabled and only few users enable that. Nowadays, this USB_USS720 driver is probably not that special that it needs to be listed as first item of the USB port drivers. Move the configuration of the USS720 parport driver to the top of the USB Miscellaneous drivers section, as the configurations does not have a lot of specific ordering USB Miscellaneous drivers. This way, the USS720 parport driver is moved to the comment "USB Miscellaneous drivers", fitting to the driver's source code location, but still is at the top of the list for those few acquainted users of Kconfig UIs that might be looking for the config that was once at the top of the list of the USB port drivers. Put this config definition to a more local place. No semantic change.

As the hidden functions reference some other symbols, make sure those are visible at compile time, at the minimal cost of a few extra bytes for 'struct usb_device'.

This isn't appropriate since only the userspace companion program to the kernel driver will know which controls are supported. Make the configfs attributes that point to those fields read/write so userspace can set them to appropriate values. Document the new behaviour at the same time so the functionality is clear.
