usb: core: Add PM runtime calls to usb_hcd_platform_shutdown

2019-05-31T13:43:48Z

[ Upstream commit 8ead7e817224d7832fe51a19783cb8fcadc79467 ] If ohci-platform is runtime suspended, we can currently get an "imprecise external abort" on reboot with ohci-platform loaded when PM runtime is implemented for the SoC. Let's fix this by adding PM runtime support to usb_hcd_platform_shutdown. Signed-off-by: Tony Lindgren Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

usb: core: Try generic PHY_MODE_USB_HOST if usb_phy_roothub_set_mode fails

2019-03-26T07:48:55Z

Some PHYs do not support PHY_MODE_USB_HOST_SS, i.e. USB 3.0 or higher. Fall back and try the more generic PHY_MODE_USB_HOST if it fails. Fixes: b97a31348379 ("usb: core: comply to PHY framework") Signed-off-by: Chen-Yu Tsai Tested-by: Neil Armstrong Signed-off-by: Greg Kroah-Hartman

usb: core: add option of only authorizing internal devices

2019-02-22T08:27:55Z

On Chrome OS we want to use USBguard to potentially limit access to USB devices based on policy. We however to do not want to wait for userspace to come up before initializing fixed USB devices to not regress our boot times. This patch adds option to instruct the kernel to only authorize devices connected to the internal ports. Previously we could either authorize all or none (or, by default, we'd only authorize wired devices). The behavior is controlled via usbcore.authorized_default command line option.

usb: core: comply to PHY framework

2019-01-30T08:22:35Z

Current implementation of the USB core does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). Signed-off-by: Miquel Raynal Signed-off-by: Greg Kroah-Hartman

usb: core: Remove unnecessary memset()

2018-12-12T11:38:41Z

register_root_hub() calls memset() setting usb_dev->bus->devmap. devicemap to 0 during hcd probe function (usb_hcd_pci_probe). But in previous function which is also the procedure of usb_hcd_pci_probe(), usb_bus_init() already initialized bus->devmap calling memset(). Furthermore, register_root_hub() is called only once in kernel. So, calling memset() which resets usb_bus->devmap.devicemap in register_root_hub() is redundant.

usb: core: remove flags variable in __usb_hcd_giveback_urb()

2018-09-11T08:14:47Z

In commit ed194d1367698 ("usb: core: remove local_irq_save() around ->complete() handler") I removed the only user of the flags variable and forgot to remove the variable, leading to warning because it is unused now. Remove the unused variable.

usb: core: remove local_irq_save() around ->complete() handler

2018-09-10T17:35:46Z

The core disabled interrupts before invocation the ->complete handler because the handler might have expected that interrupts are disabled. All handlers were audited and use proper locking now. With it, the core code no longer needs to disable interrupts before invoking the ->complete handler. Remove local_irq_save() statement before invoking the ->complete handler.
