[ Upstream commit 12f371e2b6cb4b79c788f1f073992e115f4ca918 ]

Function checkdone is only required if QUIRK2 is defined, so add
appropriate #if / #endif around the function.

Cleans up clang scan build warning:

[ Upstream commit 8774ea7a553e2aec323170d49365b59af0a2b7e0 ]

The driver already support the tcpci binding for the i2c_device_id so
add the support for the of_device_id too.

usb: typec: ucsi: Limit read size on v1.2

2024-04-13T11:10:09+00:00

[ Upstream commit b3db266fb031fba88c423d4bb8983a73a3db6527 ]

Between UCSI 1.2 and UCSI 2.0, the size of the MESSAGE_IN region was
increased from 16 to 256. In order to avoid overflowing reads for older
systems, add a mechanism to use the read UCSI version to truncate read
sizes on UCSI v1.2.

usb: gadget: uvc: mark incomplete frames with UVC_STREAM_ERR

2024-04-13T11:10:09+00:00

[ Upstream commit 2a3b7af120477d0571b815ccb8600cafd5ebf02f ]

If an frame was transmitted incomplete to the host, we set the
UVC_STREAM_ERR bit in the header for the last request that is going
to be queued. This way the host will know that it should drop the
frame instead of trying to display the corrupted content.

usb: typec: ucsi_acpi: Refactor and fix DELL quirk

2024-04-03T13:32:48+00:00

commit 6aaceb7d9cd00f3e065dc4b054ecfe52c5253b03 upstream.

Some DELL systems don't like UCSI_ACK_CC_CI commands with the
UCSI_ACK_CONNECTOR_CHANGE but not the UCSI_ACK_COMMAND_COMPLETE
bit set. The current quirk still leaves room for races because
it requires two consecutive ACK commands to be sent.

Refactor and significantly simplify the quirk to fix this:
Send a dummy command and bundle the connector change ack with the
command completion ack in a single UCSI_ACK_CC_CI command.
This removes the need to probe for the quirk.

While there define flag bits for struct ucsi_acpi->flags in ucsi_acpi.c
and don't re-use definitions from ucsi.h for struct ucsi->flags.
