- * struct spi_imx_master - device.platform_data for SPI controller devices.
- * @chipselect: Array of chipselects for this master. Numbers >= 0 mean gpio
- * pins, numbers < 0 mean internal CSPI chipselects according
- * to MXC_SPI_CS(). 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 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: ARRAY_SIZE(chipselect)
