[PATCH v1 0/3] Improve SPI target mode support and error handling

Posted by Praveen Talari 2 weeks, 2 days ago

Enhance the Qualcomm GENI SPI driver's target mode support and improve 
error handling for serial engine operations.

The current implementation has issues with incorrect controller allocation
for target mode, missing abort sequence execution during error recovery,
and lack of graceful abort mechanism for target operations. These problems
can lead to serial engine undefined behavior and improper resource
cleanup.

Fix controller allocation to use proper target APIs, ensure abort sequence
always executes for error recovery, and add target abort support for 
graceful transfer cancellation.

Praveen Talari (3):
  spi: geni-qcom: Improve target mode allocation by using proper
    allocation functions
  spi: geni-qcom: Fix abort sequence execution for serial engine errors
  spi: geni-qcom: Add target abort support
