usb: chipidea: ci_hdrc_imx: add missing put_device() call in usbmisc_get_init_data()

2021-01-12T19:16:18Z

commit 83a43ff80a566de8718dfc6565545a0080ec1fb5 upstream. if of_find_device_by_node() succeed, usbmisc_get_init_data() doesn't have a corresponding put_device(). Thus add put_device() to fix the exception handling for this function implementation.

usb: chipidea: ci_hdrc_imx: Pass DISABLE_DEVICE_STREAMING flag to imx6ul

2020-12-30T10:50:58Z

commit c7721e15f434920145c376e8fe77e1c079fc3726 upstream. According to the i.MX6UL Errata document: https://www.nxp.com/docs/en/errata/IMX6ULCE.pdf ERR007881 also affects i.MX6UL, so pass the CI_HDRC_DISABLE_DEVICE_STREAMING flag to workaround the issue.

usb: chipidea: core: add wakeup support for extcon

2020-07-22T07:33:10Z

commit 876d4e1e8298ad1f94d9e9392fc90486755437b4 upstream. If wakeup event occurred by extcon event, it needs to call ci_irq again since the first ci_irq calling at extcon notifier only wakes up controller, but do noop for event handling, it causes the extcon use case can't work well from low power mode.

usb: chipidea: msm: Ensure proper controller reset using role switch API

2020-05-14T05:58:25Z

commit 91edf63d5022bd0464788ffb4acc3d5febbaf81d upstream. Currently we check to make sure there is no error state on the extcon handle for VBUS when writing to the HS_PHY_GENCONFIG_2 register. When using the USB role-switch API we still need to write to this register absent an extcon handle. This patch makes the appropriate update to ensure the write happens if role-switching is true.

usb: chipidea: host: Disable port power only if previously enabled

2020-01-14T19:08:19Z

commit c1ffba305dbcf3fb9ca969c20a97acbddc38f8e9 upstream. On shutdown, ehci_power_off() is called unconditionally to power off each port, even if it was never called to power on the port. For chipidea, this results in a call to ehci_ci_portpower() with a request to power off ports even if the port was never powered on. This results in the following warning from the regulator code. WARNING: CPU: 0 PID: 182 at drivers/regulator/core.c:2596 _regulator_disable+0x1a8/0x210 unbalanced disables for usb_otg2_vbus Modules linked in: CPU: 0 PID: 182 Comm: init Not tainted 5.4.6 #1 Hardware name: Freescale i.MX7 Dual (Device Tree) [] (unwind_backtrace) from [] (show_stack+0x10/0x14) [] (show_stack) from [] (dump_stack+0xe0/0x10c) [] (dump_stack) from [] (__warn+0xf4/0x10c) [] (__warn) from [] (warn_slowpath_fmt+0x78/0xbc) [] (warn_slowpath_fmt) from [] (_regulator_disable+0x1a8/0x210) [] (_regulator_disable) from [] (regulator_disable+0x38/0xe8) [] (regulator_disable) from [] (ehci_ci_portpower+0x38/0xdc) [] (ehci_ci_portpower) from [] (ehci_port_power+0x50/0xa4) [] (ehci_port_power) from [] (ehci_silence_controller+0x5c/0xc4) [] (ehci_silence_controller) from [] (ehci_stop+0x3c/0xcc) [] (ehci_stop) from [] (usb_remove_hcd+0xe0/0x19c) [] (usb_remove_hcd) from [] (host_stop+0x38/0xa8) [] (host_stop) from [] (ci_hdrc_remove+0x44/0xe4) ...
