commit d7a6c0ce8d26412903c7981503bad9e1cc7c45d2 upstream.

USB Bluetooth controller QCA ROME (0cf3:e007) sometimes stops working
after S3:
[ 165.110742] Bluetooth: hci0: using NVM file: qca/nvm_usb_00000302.bin
[ 168.432065] Bluetooth: hci0: Failed to send body at 4 of 1953 (-110)

After some experiments, I found that disabling LPM can workaround the
issue.

On some platforms, the USB power is cut during S3, so the driver uses
reset-resume to resume the device. During port resume, LPM gets enabled
twice, by usb_reset_and_verify_device() and usb_port_resume().

Consolidate all checks into new LPM helpers to make sure LPM only gets
enabled once.

Fixes: de68bab4fa96 ("usb: Don't enable USB 2.0 Link PM by default.”)

<title>usb: hub: delay hub autosuspend if USB3 port is still link training</title>

[ Upstream commit e86108940e541febf35813402ff29fa6f4a9ac0b ]

When initializing a hub we want to give a USB3 port in link training
the same debounce delay time before autosuspening the hub as already
trained, connected enabled ports.

USB3 ports won't reach the enabled state with "current connect status" and
"connect status change" bits set until the USB3 link training finishes.

Catching the port in link training (polling) and adding the debounce delay
prevents unnecessary failed attempts to autosuspend the hub.

commit 91f7d2e89868fcac0e750a28230fdb1ad4512137 upstream.

The patch "usb: simplify usbport trigger" together with "leds: triggers:
add device attribute support" caused an regression for the usbport
trigger. it will no longer enumerate any active usb hub ports under the
"ports" directory in the sysfs class directory, if the usb host drivers
are fully initialized before the usbport trigger was loaded.

The reason is that the usbport driver tries to register the sysfs
entries during the activate() callback. And this will fail with -2 /
ENOENT because the patch "leds: triggers: add device attribute support"
made it so that the sysfs "ports" group was only being added after the
activate() callback succeeded.

This version of the patch reverts parts of the "usb: simplify usbport
trigger" patch and restores usbport trigger's functionality.

commit 3483254b89438e60f719937376c5e0ce2bc46761 upstream.

To match the Corsair Strafe RGB, the Corsair K70 RGB also requires
USB_QUIRK_DELAY_CTRL_MSG to completely resolve boot connection issues
discussed here: https://github.com/ckb-next/ckb-next/issues/42.
Otherwise roughly 1 in 10 boots the keyboard will fail to be detected.

commit 704620afc70cf47abb9d6a1a57f3825d2bca49cf upstream.

When reading an extra descriptor, we need to properly check the minimum
and maximum size allowed, to prevent from invalid data being sent by a
device.

<title>usb: quirk: add no-LPM quirk on SanDisk Ultra Flair device</title>

<id>urn:sha1:f025aa79bda0a963728cdd401125bffab628c5c8</id>
<content type='text'>
commit 2f2dde6ba89b1ef1fe23c1138131b315d9aa4019 upstream.

Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is
in 0781:5591, will aggressively request LPM of U1/U2 during runtime,
when using this thumb drive as the OS installation key we found the
device will generate failure during U1 exit path making it dropped
from the USB bus, this causes a corrupted installation in system at
the end.

i.e.,
[  166.918296] hub 2-0:1.0: state 7 ports 7 chg 0000 evt 0004
[  166.918327] usb usb2-port2: link state change
[  166.918337] usb usb2-port2: do warm reset
[  166.970039] usb usb2-port2: not warm reset yet, waiting 50ms
[  167.022040] usb usb2-port2: not warm reset yet, waiting 200ms
[  167.276043] usb usb2-port2: status 02c0, change 0041, 5.0 Gb/s
[  167.276050] usb 2-2: USB disconnect, device number 2
[  167.276058] usb 2-2: unregistering device
[  167.276060] usb 2-2: unregistering interface 2-2:1.0
[  167.276170] xhci_hcd 0000:00:15.0: shutdown urb ffffa3c7cc695cc0 ep1in-bulk
[  167.284055] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK
[  167.284064] sd 0:0:0:0: [sda] tag#0 CDB: Read(10) 28 00 00 33 04 90 00 01 00 00
...

Analyzed the USB trace in the link layer we realized it is because
of the 6-ms timer of tRecoveryConfigurationTimeout which documented
on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from
Recovery.Configuration"; device initiates U1 exit -&gt; Recovery.Active
-&gt; Recovery.Configuration, then the host timer timeout makes the link
transits to eSS.Inactive -&gt; Rx.Detect follows by a Warm Reset.

Interestingly, the other higher volume of SanDisk Ultra Flair sharing
the same VID:PID, such as 64GB, would not request LPM during runtime,
it sticks at U0 always, thus disabling LPM does not affect those thumb
drives at all.

The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

Cherry G230 Stream 2.0 (G85-231) and 3.0 (G85-232) need this quirk to
function correctly. This fixes a but where double pressing numlock locks
up the device completely with need to replug the keyboard.

commit 22454b79e6de05fa61a2a72d00d2eed798abbb75 upstream.

This will clear the USB_PORT_FEAT_C_CONNECTION bit in case of a hub port reset
only if a device is was attached to the hub port before resetting the hub port.

Using a Lenovo T480s attached to the ultra dock it was not possible to detect
some usb-c devices at the dock usb-c ports because the hub_port_reset code
will clear the USB_PORT_FEAT_C_CONNECTION bit after the actual hub port reset.
Using this device combo the USB_PORT_FEAT_C_CONNECTION bit was set between the
actual hub port reset and the clear of the USB_PORT_FEAT_C_CONNECTION bit.
This ends up with clearing the USB_PORT_FEAT_C_CONNECTION bit after the
new device was attached such that it was not detected.

This patch will not clear the USB_PORT_FEAT_C_CONNECTION bit if there is
currently no device attached to the port before the hub port reset.
This will avoid clearing the connection bit for new attached devices.
