[PATCH 0/2] spi: qcom-geni: Use GPIO to notify master of SPI target activity

[Praveen Talari]

When operating in SPI target mode, the GENI controller relies on an
external GPIO to notify the SPI master about the target's active state.

Add support for an optional device GPIO that is asserted when a target
transfer begins and deasserted when the transfer completes, is aborted,
or hits a timeout. This allows the target to explicitly signal its
availability to the master and ensures the GPIO is released in all error
and completion paths, preventing the master from observing a stale or
incorrect target-ready indication.

The GPIO is optional and requested only when target mode is enabled,
using devm_gpiod_get_index_optional() so targets without this signal
continue to work unchanged.
