- * struct spi_imx_master - device.platform_data for SPI controller devices.
- * @chipselect: Array of chipselects for this master or NULL.  Numbers >= 0
- *              mean GPIO pins, -ENOENT means internal CSPI chipselect
- *              matching the position in the array.  E.g., if chipselect[1] =
- *              -ENOENT then a SPI slave using chip select 1 will use the
- *              native SS1 line of the CSPI.  Omitting the array will use
- *              all native chip selects.
-
- *              Normally you want to use gpio based chip selects as the CSPI
- *              module tries to be intelligent about when to assert the
- *              chipselect:  The CSPI module deasserts the chipselect once it
- *              runs out of input data.  The other problem is that it is not
- *              possible to mix between high active and low active chipselects
- *              on one single bus using the internal chipselects.
- *              Unfortunately, on some SoCs, Freescale decided to put some
- *              chipselects on dedicated pins which are not usable as gpios,
- *              so we have to support the internal chipselects.
- *
- * @num_chipselect: If @chipselect is specified, ARRAY_SIZE(chipselect),
- *                  otherwise the number of native chip selects.
