USB: Extend pci resume function to handle PM events

2023-05-13T08:33:18+00:00

Currently, the pci_resume method has only a flag indicating whether the system is resuming from hibernation. In order to handle all PM events like AUTO_RESUME (runtime resume from device in D3), RESUME (system resume from s2idle, S3 or S4 states) etc change the pci_resume method to handle all PM events.

USB: hcd-pci: Drop the unused id parameter from usb_hcd_pci_probe()

2022-09-01T14:08:35+00:00

Since the HC driver is now passed to the function with its own parameter (it used to be picked from id->driver_data), the id parameter serves no purpose.

usb: reduce kernel log spam on driver registration

2022-08-31T07:07:53+00:00

Drivers are typically supposed to be quiet unless they are actually probed, but for some reason, USB host controllers seem to be exempt from this rule, and happily broadcast their existence into the kernel log at boot even if the hardware in question is nowhere to be found. Let's fix that, and remove these pr_info() calls.

USB: OHCI: remove obsolete FIXME comment

This comment has been present since the start of git. Since no one is going to do anything about it, and all seems to work well, just drop the thing entirely. Cc: Alan Stern Link: https://lore.kernel.org/r/20200618094300.1887727-4-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman

usb: hci: add hc_driver as argument for usb_hcd_pci_probe

2020-05-15T13:44:34+00:00

usb_hcd_pci_probe expects users to call this with driver_data set as hc_driver, that limits the possibility of using the driver_data for driver data. Add hc_driver as argument to usb_hcd_pci_probe and modify the callers ehci/ohci/xhci/uhci to pass hc_driver as argument and freeup the driver_data used Tested xhci driver on Dragon-board RB3, compile tested ehci, ohci and uhci.

usb: host: ohci-pci: remove useless cast for driver.name

pci_driver name is const char pointer, so it not useful to cast hcd_name (which is already const char). Signed-off-by: Corentin Labbe Link: https://lore.kernel.org/r/1582054383-35760-17-git-send-email-clabbe@baylibre.com Signed-off-by: Greg Kroah-Hartman

usb: pci-quirks: Minor cleanup for AMD PLL quirk

2019-07-25T08:40:02+00:00

usb_amd_find_chipset_info() is used for chipset detection for several quirks. It is strange that its return value indicates the need for the PLL quirk, which means it is often ignored. This patch adds a function specifically for checking the PLL quirk like the other ones. Additionally, rename probe_result to something more appropriate.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

ohci-pci: add qemu quirk

2017-03-23T07:13:21+00:00

On a loaded virtualization host (dozen guests booting at the same time) it may happen that the ohci controller emulation doesn't manage to do timely frame processing, with the result that the io watchdog fires and considers the controller being dead, even though it's only the emulation being unusual slow due to the load peak. So, add a quirk for qemu and don't use the watchdog in case we figure we are running on emulated ohci. The virtual ohci controller masquerades as apple ohci controller, but we can identify it by subsystem id.
