-/**
- * spi_setup - setup SPI mode and clock rate
- * @spi: the device whose settings are being modified
- * Context: can sleep, and no requests are queued to the device
- *
- * SPI protocol drivers may need to update the transfer mode if the
- * device doesn't work with its default.  They may likewise need
- * to update clock rates or word sizes from initial values.  This function
- * changes those settings, and must be called from a context that can sleep.
- * Except for SPI_CS_HIGH, which takes effect immediately, the changes take
- * effect the next time the device is selected and data is transferred to
- * or from it.  When this function returns, the spi device is deselected.
- *
- * Note that this call will fail if the protocol driver specifies an option
- * that the underlying controller or its driver does not support.  For
- * example, not all hardware supports wire transfers using nine bit words,
- * LSB-first wire encoding, or active-high chipselects.
