No response is observed when spi-slave mode is set on imx6

[amit_priye]

Hi,

We have applied the patch provided on below link to enable spi slave mode .

How to support spi slave in kernel4.1.15 & imx6? 

Spi driver is probed successfully , When we connect is to spi master device and spi master device send data nothing is observed  in dmesg .

From hardware prospective we have verified that spi-master data  and clock properly send the spi slave line .

Our actual requirement is to make imx6 as slave and microcontroller as master which sent data on spi line .We need read and write through the
spi-slave (ie imx6 ).Any suggestion related to this please provide the same .

Thanks

our BSP is not support SPI slave mode.
Only kernel 4.15 and 4.16 from mainline supports it.

In order to use SPI slave in these kernels the "spi-slave" property needs to be passed in the devicetree as explained at:
