usb: gadget: fsl_qe_udc: validate endpoint index for ch9 udc

2023-09-23T09:00:05+00:00

[ Upstream commit ce9daa2efc0872a9a68ea51dc8000df05893ef2e ]

We should verify the bound of the array to assure that host
may not manipulate the index to point past endpoint array.

usb: typec: bus: verify partner exists in typec_altmode_attention

2023-09-23T09:00:01+00:00

[ Upstream commit f23643306430f86e2f413ee2b986e0773e79da31 ]

Some usb hubs will negotiate DisplayPort Alt mode with the device
but will then negotiate a data role swap after entering the alt
mode. The data role swap causes the device to unregister all alt
modes, however the usb hub will still send Attention messages
even after failing to reregister the Alt Mode. type_altmode_attention
currently does not verify whether or not a device's altmode partner
exists, which results in a NULL pointer error when dereferencing
the typec_altmode and typec_altmode_ops belonging to the altmode
partner.

Verify the presence of a device's altmode partner before sending
the Attention message to the Alt Mode driver.

usb: typec: tcpm: Refactor tcpm_handle_vdm_request

2023-09-23T09:00:01+00:00

[ Upstream commit 95b4d51c96a87cd760c2a4f27fb28a59a27b6368 ]

Refactor tcpm_handle_vdm_request and its tcpm_pd_svdm helper function so
that reporting the results of the vdm to the altmode-driver is separated
out into a clear separate step inside tcpm_handle_vdm_request, instead
of being scattered over various places inside the tcpm_pd_svdm helper.

This is a preparation patch for fixing an AB BA lock inversion between the
tcpm code and some altmode drivers.

usb: typec: tcpm: Refactor tcpm_handle_vdm_request payload handling

2023-09-23T09:00:00+00:00

[ Upstream commit 8afe9a3548f9d1805dcea6d97978f2179c8403a3 ]

Refactor the tcpm_handle_vdm_request payload handling by doing the
endianness conversion only once directly inside tcpm_handle_vdm_request
itself instead of doing it multiple times inside various helper functions
called by tcpm_handle_vdm_request.

This is a preparation patch for some further refactoring to fix an AB BA
lock inversion between the tcpm code and some altmode drivers.

usb: typec: tcpci: clear the fault status bit

2023-09-23T08:59:56+00:00

[ Upstream commit 23e60c8daf5ec2ab1b731310761b668745fcf6ed ]

According the "USB Type-C Port Controller Interface Specification v2.0"
the TCPC sets the fault status register bit-7
(AllRegistersResetToDefault) once the registers have been reset to
their default values.

This triggers an alert(-irq) on PTN5110 devices albeit we do mask the
fault-irq, which may cause a kernel hang. Fix this generically by writing
a one to the corresponding bit-7.

usb: phy: mxs: fix getting wrong state with mxs_phy_is_otg_host()

2023-09-23T08:59:49+00:00

[ Upstream commit 5eda42aebb7668b4dcff025cd3ccb0d3d7c53da6 ]

The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is
0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real
state if the ID pin is float, such as Host-only or Type-C cases. The value
of OTG_ID_VALUE is always 1 which means device mode.
This patch will fix the issue by judging the current mode based on
last_event. The controller will update last_event in time.

USB: dwc3: qcom: fix NULL-deref on suspend

2023-08-30T14:27:13+00:00

[ Upstream commit d2d69354226de0b333d4405981f3d9c41ba8430a ]

The Qualcomm dwc3 glue driver is currently accessing the driver data of
the child core device during suspend and on wakeup interrupts. This is
clearly a bad idea as the child may not have probed yet or could have
been unbound from its driver.

The first such layering violation was part of the initial version of the
driver, but this was later made worse when the hack that accesses the
driver data of the grand child xhci device to configure the wakeup
interrupts was added.

Fixing this properly is not that easily done, so add a sanity check to
make sure that the child driver data is non-NULL before dereferencing it
for now.

Note that this relies on subtleties like the fact that driver core is
making sure that the parent is not suspended while the child is probing.
