Title:
Pull request to address TPM SPI devices
Status in linux-nvidia-6.5 package in Ubuntu:
Fix Committed
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.
