usb: do not reset if a low-speed or full-speed device timed out

2018-07-03T09:26:47Z

commit 6e01827ed93947895680fbdad68c072a0f4e2450 upstream. Some low-speed and full-speed devices (for example, bluetooth) do not have time to initialize. For them, ETIMEDOUT is a valid error. We need to give them another try. Otherwise, they will never be initialized correctly and in dmesg will be messages "Bluetooth: hci0 command 0x1002 tx timeout" or similars.

usb: gadget: udc: renesas_usb3: disable the controller's irqs for reconnecting

2018-06-16T07:18:21Z

commit bd6bce004d78b867ba0c6d3712f1c5b50398af9a upstream. This patch fixes an issue that reconnection is possible to fail because unexpected state handling happens by the irqs. To fix the issue, the driver disables the controller's irqs when disconnected.

usb: gadget: udc: renesas_usb3: should fail if devm_phy_get() returns error

2018-06-16T07:18:21Z

commit 0259068f63f23a665ded28647f2f9cdb6b20dc72 upstream. This patch fixes an issue that this driver ignores errors other than the non-existence of the device, f.e. a memory allocation failure in devm_phy_get(). So, this patch replaces devm_phy_get() with devm_phy_optional_get().

usb: gadget: udc: renesas_usb3: should call devm_phy_get() before add udc

2018-06-16T07:18:21Z

commit 003bc1dee216b1fb8e02040a95672bea0f1fe797 upstream. This patch fixes an issue that this driver cannot call phy_init() if a gadget driver is alreadly loaded because usb_add_gadget_udc() might call renesas_usb3_start() via .udc_start. This patch also revises the typo (s/an optional/optional/).

usb: gadget: udc: renesas_usb3: should call pm_runtime_enable() before add udc

commit d998844016b24a8d71b9aa5eae7e51d70f2de438 upstream. This patch fixes an issue that this driver causes panic if a gadget driver is already loaded because usb_add_gadget_udc() might call renesas_usb3_start() via .udc_start, and then pm_runtime_get_sync() in renesas_usb3_start() doesn't work correctly. Note that the usb3_to_dev() macro should not be called at this timing because the macro uses the gadget structure.

This driver must not call phy_put() in the remove because the driver calls devm_phy_get() in the probe.

usb: gadget: function: printer: avoid wrong list handling in printer_write()

2018-06-16T07:18:21Z

commit 4a014a7339f441b0851ce012f469c0fadac61c81 upstream. When printer_write() calls usb_ep_queue(), a udc driver (e.g. renesas_usbhs driver) may call usb_gadget_giveback_request() in the udc .queue ops immediately. Then, printer_write() calls list_add(&req->list, &dev->tx_reqs_active) wrongly. After that, if we do unbind the printer driver, WARN_ON() happens in printer_func_unbind() because the list entry is not removed. So, this patch moves list_add(&req->list, &dev->tx_reqs_active) calling before usb_ep_queue(). Signed-off-by: Yoshihiro Shimoda Acked-by: Felipe Balbi Cc: stable Signed-off-by: Greg Kroah-Hartman

usb: typec: wcove: Remove dependency on HW FSM

2018-06-16T07:18:21Z

commit 05826ff135ee083d28c006fbde6e810f17437166 upstream. The USB Type-C PHY in Intel WhiskeyCove PMIC has build-in USB Type-C state machine which we were relying on to configure the CC lines correctly. This patch removes that dependency and configures the CC line according to commands from the port manager (tcpm.c) in wcove_set_cc(). This fixes an issue where USB devices attached to the USB Type-C port do not get enumerated. When acting as source/host, the HW FSM sometimes fails to configure the PHY correctly.
