Accessing IMX6 spi in kernel space

kiruthikavarada — Wed, 22 Apr 2015 06:56:43 GMT

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,

Hi kiruthika

to access in kernel space one can write kernel test application (driver),

as for example described below

Best regards
