[PATCH 2/2] spi: cadence-quadspi: Use STIG mode for all ops with small payload

2023-03-23 Thread Dhruva Gole
OSPI controller supports all types of op variants in STIG mode, only limitation being that the data payload should be less than 8 bytes when not using memory banks. STIG mode is more stable for operations that send small data payload and is more efficient than using DMA for few bytes of memory
