UPSTREAM: usb: dwc3: gadget: Avoid duplicate requests to enable Run/Stop
Relocate the pullups_connected check until after it is ensured that there
are no runtime PM transitions. If another context triggered the DWC3
core's runtime resume, it may have already enabled the Run/Stop. Do not
re-run the entire pullup sequence again, as it may issue a core soft
reset while Run/Stop is already set.
This patch depends on
commit 69e131d1ac4e ("usb: dwc3: gadget: Prevent repeat pullup()")
Fixes: 77adb8bdf422 ("usb: dwc3: gadget: Allow runtime suspend if UDC unbinded")

UPSTREAM: usb: typec: ucsi: Acknowledge the GET_ERROR_STATUS command completion
We found PPM will not send any notification after it report error status
and OPM issue GET_ERROR_STATUS command to read the details about error.
According UCSI spec, PPM may clear the Error Status Data after the OPM
has acknowledged the command completion.
This change add operation to acknowledge the command completion from PPM.

FROMGIT: usb: dwc3: core: Do not perform GCTL_CORE_SOFTRESET during bootup
According to the programming guide, it is recommended to
perform a GCTL_CORE_SOFTRESET only when switching the mode
from device to host or host to device. However, it is found
that during bootup when __dwc3_set_mode() is called for the
first time, GCTL_CORESOFTRESET is done with suspendable bit(BIT 17)
of DWC3_GUSB3PIPECTL set. This some times leads to issues
like controller going into bad state and controller registers
reading value zero. Until GCTL_CORESOFTRESET is done and
run/stop bit is set core initialization is not complete.
Setting suspendable bit of DWC3_GUSB3PIPECTL and then
performing GCTL_CORESOFTRESET is therefore not recommended.
Avoid this by only performing the reset if current_dr_role is set,
that is, when doing subsequent role switching.

FROMGIT: usb: dwc3: gadget: Prevent repeat pullup()
Don't do soft-disconnect if it's previously done. Likewise, don't do soft-connect if the device is currently connected and running. It would break normal operation. Currently the caller of pullup() (udc's sysfs soft_connect) only checks if it had initiated disconnect to prevent repeating soft-disconnect. It doesn't check for soft-connect. To be safe, let's keep the check here regardless whether the udc core is fixed.

UPSTREAM: usb: gadget: u_audio: Rate ctl notifies about current srate (0=stopped)
The Playback/Capture ctl currently reports rate value set by USB control selector UAC2_CS_CONTROL_SAM_FREQ (fixed for UAC1). When the stops playback/capture, the reported value does not change. The gadget side has no information whether the host has started/stopped capture/playback. This patch sets the value reported by the respective rate ctl to zero when the host side has stopped playback/capture. Also, it calls snd_ctl_notify when start/stop occurs, so that a subscribed client can act appropriately. Tests have confirmed that USB hosts change UAC2_CS_CONTROL_SAM_FREQ before switching altsetting to activate playback/capture, resulting in correct order (params->c/p_srate is set to requested rate before u_audio_start_capture/playback is called). The gadget rate notifications are used by user-space audio gadget controller gaudio_ctl https://github.com/pavhofman/gaudio_ctl.

UPSTREAM: usb: gadget: u_audio: fix calculations for small bInterval
If bInterval is 1, then p_interval is 8000 and p_interval_mil is 8E9,
which is too big for a 32-bit value. While the storage is indeed
64-bit, this value is used as the divisor in do_div() which will
truncate it into a uint32_t leading to incorrect calculated values.
Switch back to keeping the base value in struct snd_uac_chip which fits
easily into an int, meaning that the division can be done in two steps
with the divisor fitting safely into a uint32_t on both steps.

UPSTREAM: usb: gadget: u_audio.c: Adding Playback Pitch ctl for sync playback
EP IN is hard-coded as ASYNC both in f_uac1 and f_uac2 but u_audio sends steady number of audio frames in each USB packet, without any control. This patch adds 'Playback Pitch 1000000' ctl analogous to the existing 'Capture Pitch 1000000' ctl. The calculation of playback req->length in u_audio_iso_complete respects the Playback Pitch ctl value to 1ppm now. Max. value for Playback Pitch is configured by the existing parameter uac2_opts->fb_max, used also for the Capture Pitch. Since the EP IN packet size can be increased by uac2_opts->fb_max now, maxPacketSize for the playback direction is calculated by the same algorithm as for the async capture direction in f_uac2.c:set_ep_max_packet_size.

UPSTREAM: usb: gadget: u_audio: add bi-directional volume and mute support
USB Audio Class 1/2 have ability to change device's volume and mute by USB Host through class-specific control requests. Device also can notify Host about volume/mute change on its side through optional interrupt endpoint. This patch adds Volume and Mute ALSA controls which can be used by user to send and receive notifications to/from the USB Host about Volume and Mute change.

Currently the VBUS/ID detection interrupts are disabled during system suspend. So the USB cable connect/disconnect event can't wakeup the system from low power mode. To allow this, we keep these interrupts enabled and configure them as wakeup capable. This behavior can be controlled through device wakeup source policy by the user space. This was tested and verified on a target.

FROMGIT: usb: gadget: uvc: calculate the number of request depending on framesize
The current limitation of possible number of requests being handled is
dependent on the gadget speed. It makes more sense to depend on the
typical frame size when calculating the number of requests. This patch
is changing this and is using the previous limits as boundaries for
reasonable minimum and maximum number of requests.
For a 1080p jpeg encoded video stream with a maximum imagesize of
e.g. 800kB with a maxburst of 8 and an multiplier of 1 the resulting
number of requests is calculated to 49.

usb: gadget: uvc: allow for application to cleanly shutdown
commit b81ac4395bbeaf36e078dea1a48c02dd97b76235 upstream. Several types of kernel panics can occur due to timing during the uvc gadget removal. This appears to be a problem with gadget resources being managed by both the client application's v4l2 open/close and the UDC gadget bind/unbind. Since the concept of USB_GADGET_DELAYED_STATUS doesn't exist for unbind, add a wait to allow for the application to close out. Some examples of the panics that can occur are: <1>[ 1147.652313] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028 <4>[ 1147.652510] Call trace: <4>[ 1147.652514] usb_gadget_disconnect+0x74/0x1f0 <4>[ 1147.652516] usb_gadget_deactivate+0x38/0x168 <4>[ 1147.652520] usb_function_deactivate+0x54/0x90 <4>[ 1147.652524] uvc_function_disconnect+0x14/0x38 <4>[ 1147.652527] uvc_v4l2_release+0x34/0xa0 <4>[ 1147.652537] __fput+0xdc/0x2c0 <4>[ 1147.652540] ____fput+0x10/0x1c <4>[ 1147.652545] task_work_run+0xe4/0x12c <4>[ 1147.652549] do_notify_resume+0x108/0x168 <1>[ 282.950561][ T1472] Unable to handle kernel NULL pointer dereference at virtual address 00000000000005b8 <6>[ 282.953111][ T1472] Call trace: <6>[ 282.953121][ T1472] usb_function_deactivate+0x54/0xd4 <6>[ 282.953134][ T1472] uvc_v4l2_release+0xac/0x1e4 <6>[ 282.953145][ T1472] v4l2_release+0x134/0x1f0 <6>[ 282.953167][ T1472] __fput+0xf4/0x428 <6>[ 282.953178][ T1472] ____fput+0x14/0x24 <6>[ 282.953193][ T1472] task_work_run+0xac/0x130 <3>[ 213.410077][ T29] configfs-gadget gadget: uvc: Failed to queue request (-108). <1>[ 213.410116][ T29] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000003 <6>[ 213.413460][ T29] Call trace: <6>[ 213.413474][ T29] uvcg_video_pump+0x1f0/0x384 <6>[ 213.413489][ T29] process_one_work+0x2a4/0x544 <6>[ 213.413502][ T29] worker_thread+0x350/0x784 <6>[ 213.413515][ T29] kthread+0x2ac/0x320 <6>[ 213.413528][ T29] ret_from_fork+0x10/0x30 Signed-off-by: Dan Vacura <w36195@motorola.com> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20220503201039.71720-1-w36195@motorola.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

USB: serial: option: add Fibocom MA510 modem
commit 07989eb981d862f7f2be68d233d753f2e7ccc119 upstream.
The MA510 modem has 3 USB configurations that are configurable via the AT
command AT+GTUSBMODE={30,31,32} which make the modem enumerate with the
following interfaces, respectively:
30: Diag + QDSS + Modem + RMNET
31: Diag + Modem + AT + ECM
32: Modem + AT + ECM
The first configuration (30) reuses u-blox R410M's VID/PID with
identical interface configuration.
A detailed description of the USB configuration for each mode follows:

USB: serial: option: add Fibocom L610 modem
commit 714adff9a6271b5f1664b04c944b598141ebfe73 upstream.
The L610 modem has 3 USB configurations that are configurable via the AT
command AT+GTUSBMODE={31,32,33} which make the modem enumerate with the
following interfaces, respectively:
31: Modem + NV + MOS + Diag + LOG + AT + AT
32: ECM + Modem + NV + MOS + Diag + LOG + AT + AT
33: RNDIS + Modem + NV + MOS + Diag + LOG + AT + AT
A detailed description of the USB configuration for each mode follows:

usb: typec: tcpci_mt6360: Update for BMC PHY setting
commit 4031cd95cba70c72e4cadc2d46624bcd31e5a6c0 upstream.
Update MT6360 BMC PHY Tx/Rx setting for the compatibility.
Macpaul reported this CtoDP cable attention message cannot be received from
MT6360 TCPC. But actually, attention message really sent from UFP_D
device.
After RD's comment, there may be BMC PHY Tx/Rx setting causes this issue.
Below's the detailed TCPM log and DP attention message didn't received from 6360
TCPCI.

usb: typec: tcpci: Don't skip cleanup in .remove() on error
commit bbc126ae381cf0a27822c1f822d0aeed74cc40d9 upstream.
Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.
In this case the remove callback even returns early without stopping the
tcpm worker thread and various timers. A work scheduled on the work
queue, or a firing timer after tcpci_remove() returned probably results
in a use-after-free situation because the regmap and driver data were
freed. So better make sure that tcpci_unregister_port() is called even
if disabling the irq failed.
Also emit a more specific error message instead of the i2c core's
"remove failed (EIO), will be ignored" and return 0 to suppress the
core's warning.
This patch is (also) a preparation for making i2c remove callbacks
return void.

usb: cdc-wdm: fix reading stuck on device close
commit 01e01f5c89773c600a9f0b32c888de0146066c3a upstream.
cdc-wdm tracks whether a response reading request is in-progress and
blocks the next request from being sent until the previous request is
completed. As soon as last user closes the cdc-wdm device file, the
driver cancels any ongoing requests, resets the pending response
counter, but leaves the response reading in-progress flag
(WDM_RESPONDING) untouched.
So if the user closes the device file during the response receive
request is being performed, no more data will be obtained from the
modem. The request will be cancelled, effectively preventing the
WDM_RESPONDING flag from being reseted. Keeping the flag set will
prevent a new response receive request from being sent, permanently
blocking the read path. The read path will staying blocked until the
module will be reloaded or till the modem will be re-attached.
This stuck has been observed with a Huawei E3372 modem attached to an
OpenWrt router and using the comgt utility to set up a network
connection.
Fix this issue by clearing the WDM_RESPONDING flag on the device file
close.
Without this fix, the device reading stuck can be easily reproduced in a
few connection establishing attempts. With this fix, a load test for
modem connection re-establishing worked for several hours without any
issues.

FROMGIT: usb: gadget: uvc: allow for application to cleanly shutdown
Several types of kernel panics can occur due to timing during the uvc gadget removal. This appears to be a problem with gadget resources being managed by both the client application's v4l2 open/close and the UDC gadget bind/unbind. Since the concept of USB_GADGET_DELAYED_STATUS doesn't exist for unbind, add a wait to allow for the application to close out. Some examples of the panics that can occur are: <1>[ 1147.652313] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028 <4>[ 1147.652510] Call trace: <4>[ 1147.652514] usb_gadget_disconnect+0x74/0x1f0 <4>[ 1147.652516] usb_gadget_deactivate+0x38/0x168 <4>[ 1147.652520] usb_function_deactivate+0x54/0x90 <4>[ 1147.652524] uvc_function_disconnect+0x14/0x38 <4>[ 1147.652527] uvc_v4l2_release+0x34/0xa0 <4>[ 1147.652537] __fput+0xdc/0x2c0 <4>[ 1147.652540] ____fput+0x10/0x1c <4>[ 1147.652545] task_work_run+0xe4/0x12c <4>[ 1147.652549] do_notify_resume+0x108/0x168 <1>[ 282.950561][ T1472] Unable to handle kernel NULL pointer dereference at virtual address 00000000000005b8 <6>[ 282.953111][ T1472] Call trace: <6>[ 282.953121][ T1472] usb_function_deactivate+0x54/0xd4 <6>[ 282.953134][ T1472] uvc_v4l2_release+0xac/0x1e4 <6>[ 282.953145][ T1472] v4l2_release+0x134/0x1f0 <6>[ 282.953167][ T1472] __fput+0xf4/0x428 <6>[ 282.953178][ T1472] ____fput+0x14/0x24 <6>[ 282.953193][ T1472] task_work_run+0xac/0x130 <3>[ 213.410077][ T29] configfs-gadget gadget: uvc: Failed to queue request (-108). <1>[ 213.410116][ T29] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000003 <6>[ 213.413460][ T29] Call trace: <6>[ 213.413474][ T29] uvcg_video_pump+0x1f0/0x384 <6>[ 213.413489][ T29] process_one_work+0x2a4/0x544 <6>[ 213.413502][ T29] worker_thread+0x350/0x784 <6>[ 213.413515][ T29] kthread+0x2ac/0x320 <6>[ 213.413528][ T29] ret_from_fork+0x10/0x30 Signed-off-by: Dan Vacura <w36195@motorola.com> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20220503201039.71720-1-w36195@motorola.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Bug: 229140375 (cherry picked from commit b81ac4395bbeaf36e078dea1a48c02dd97b76235 https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-linus) Signed-off-by: Dan Vacura <w36195@motorola.com> Change-Id: I451813637a02429041aa34ce9cb4cbd63c557415 |

UPSTREAM: usb: gadget: configfs: clear deactivation flag in configfs_composite_unbind()
If any function like UVC is deactivating gadget as part of composition switch which results in not calling pullup enablement, it is not getting enabled after switch to new composition due to this deactivation flag not cleared. This results in USB enumeration not happening after switch to new USB composition. Hence clear deactivation flag inside gadget structure in configfs_composite_unbind() before switch to new USB composition.

FROMGIT: usb: gadget: uvc: remove pause flag use
The pause flag doesn't appear to serve a purpose as it is possible for the pump worker thread to not be running when new buffers are queued. Before the following change was introduced: "43cd0023872e usb: gadget: uvc_video: add worker to handle the frame pumping", the pause flag status was discarded and never returned. This masked a current issues of the userspace receiving non-zero values (considered unsuccessful) and prevents trace_v4l2_qbuf() from being called.
