Hi All,

  Currently IMX6 spi master is working with spidev driver and user application.

 

  How can I access the driver in kernel space itself?? I want to send some commands for system halt through SPI.

  Where can I obtain spi_device pointer?? Can I use  to_spi_device(dev) with dev information from platform_data.

 

  Suggest me the way to get spi_device pointer in kernel.

 

Thanks,
