/****************************************************************************
* Name: stm32_spi1/2/...register
*
* Description:
* If the board supports a card detect callback to inform the SPI-based
* MMC/SD drvier when an SD card is inserted or removed, then
* CONFIG_SPI_CALLBACK should be defined and the following function(s) must
* be implemented. These functiosn implements the registercallback method
* of the SPI interface (see include/nuttx/spi/spi.h for details)
*
* Input Parameters:
* dev - Device-specific state data
* callback - The funtion to call on the media change
* arg - A caller provided value to return with the callback
*
* Returned Value:
* 0 on success; negated errno on failure.
