Bug Description

TPM devices may insert wait state on last clock cycle of ADDR phase.
For SPI controllers that support full-duplex transfers, this can be
detected using software by reading the MISO line. For SPI controllers
that only support half-duplex transfers, such as the Tegra QSPI, it is
not possible to detect the wait signal from software.

This bug is awaiting verification that the linux-nvidia-6.5/6.5.0-1010.10 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-nvidia-6.5' to 'verification-done-jammy-linux-nvidia-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-nvidia-6.5' to 'verification-failed-jammy-linux-nvidia-6.5'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
