usb: mtu3: fix error of xhci port id when enable U3 dual role

2018-09-26T06:39:32+00:00

commit 78af87b8bbbbcaa613f1a7d8f14472fe9a7dc622 upstream. If dual role mode is enabled, when switch u3port0 to device mode, it will affect port id calculation of host(xHCI), specially when host supports multi U2 ports or U3 ports, so need enable its dual role mode, and fix it here.

USB: mtu3: no need to check return value of debugfs_create_dir()

2018-05-31T10:54:21+00:00

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Cc: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: fix warning of sleep in atomic context in notifier callback

2018-05-24T16:09:37+00:00

The notifier callbacks of extcon are called in atomic context, but the callbacks will call regulator_enable()/regulator_disable() which may sleep caused by mutex, so use work queue to call the sleep functions. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: reset gadget when VBUS_FALL interrupt arises

2018-05-24T16:09:37+00:00

When VBUS_FALL interrupt arises, it means U3 device is disconnected with host, so need reset status of gadget Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: avoid sleep in atomic context when enter test mode

2018-05-24T16:09:37+00:00

Use readl_poll_timeout_atomic() instead of readl_poll_timeout() in atomic context Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: clear test_mode flag when reset

2018-05-24T16:09:37+00:00

Clear test_mode flag when the gadget is reset by host, otherwise will affect the next test item. Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: fix uncontinuous SeqN issue after disable EP

2018-05-24T16:09:37+00:00

Reset EP when disable it to reset data toggle for U2 EP, and SeqN, flow control status etc for U3 EP, this can avoid issue of uncontinuous SeqN Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

usb: mtu3: re-enable controller to accept LPM request after LPM resume

2018-05-24T16:09:36+00:00

After the controller receives a LPM request, it will reject the LPM request, and need software to re-enable it after LPM resume if the controller doesn't remote wakeup from L1 automatically Signed-off-by: Chunfeng Yun Signed-off-by: Greg Kroah-Hartman

Merge tag 'usb-for-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

usb: changes for v4.18 merge window A total of 98 non-merge commits, the biggest part being in dwc3 this time around with a large refactoring of dwc3's transfer handling code. We also have a new driver for Aspeed virtual hub controller. Apart from that, just a list of miscellaneous fixes all over the place.

usb: mtu3: make USB_MTU3_DUAL_ROLE depend on EXTCON but not USB_MTU3

2018-05-15T07:15:10+00:00

In fact the driver depends on EXTCON only when it's configed as USB_MTU3_DUAL_ROLE, so make USB_MTU3_DUAL_ROLE depend on EXTCON but not USB_MTU3. Signed-off-by: Chunfeng Yun Signed-off-by: Felipe Balbi
