spi: orion: use new `word_delay` field for SPI transfers (21e26062) · Commits · 戴 / test

The `word_delay` field had it's type changed to `struct spi_delay`. This allows users to specify nano-second or clock-cycle delays (if needed). Converting to use `word_delay` is straightforward: it just uses the new `spi_delay_exec()` routine, that handles the `unit` part. Signed-off-by:
