I have attached a patch that shows implementation for slave mode. This was done for MX51, but should be similar for MX53. Hope this helps.

Hi Sanjeev,

The patch that was attached is to make the MX6 behave as a SPI slave device. By default, the driver provided in the BSP configures the MX6 SPI to be master.

So if you have a SPI slave device with MX6 as SPI master, then you do not need this patch.

Best regards,

Should work on MX6 as well since the same eCSPI module is present on MX6. You will have to port it to the driver that is included as part of the MX6 BSP.
