spi: tegra210-quad: Improve timeout handling under
Merge series from Vishwaroop A <va@nvidia.com>:
This patch series addresses timeout handling issues in the Tegra QSPI driver
that occur under high system load conditions. We've observed that when CPUs
are saturated (due to error injection, RAS firmware activity, or general CPU
contention), QSPI interrupt handlers can be delayed, causing spurious transfer
failures even though the hardware completed the operation successfully.
These changes have been tested in production environments under various high
load scenarios including RAS testing and CPU saturation workloads.
