Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories.

* 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.
