Subject: [PATCH v4 06/19] spi: spidev: use new `word_delay` field for spi transfers
Date: Thu, 26 Sep 2019 13:51:34 +0300 [thread overview]
Message-ID: <20190926105147.7839-7-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20190926105147.7839-1-alexandru.ardelean@analog.com>
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's just assigning the
value to `word_delay.value` and hard-coding the `word_delay.unit` to
`SPI_DELAY_UNIT_USECS`
This keeps the uapi for spidev un-changed. Changing it can be part of
another changeset and discussion.
