## Summary This commit adds support for `SPI_SETDELAY` operation on SAMv7 QSPI peripheral running in SPI mode. The logic is the same as for standard SPI peripheral, just different registers. The change allows to set custom delays between transfers, chip selects and so on. ## Impact None on current implementations with `CONFIG_SPI_DELAY_CONTROL` disabled. If enabled, it allows to set SPI delays based on the device settings. ## Testing Tested against W25 SPI NOR flash on a custom SAMv7 board. Flash had SmartFS partition and three partitions for NXboot. The update and confirmation process was significantly slower because of default large delay between consecutive transfers. The speed is as expected with the delays set to zero. The needed change in W25 driver is in #17388 17388 -- This is an automated message from the Apache Git Service.
