TK1 SPI Slave Driver

According to the Apalis TK1 Datasheet SPI3 can be used as an SPI Slave.

I was looking through the toradex-linux source, but it I couldn’t find the SPI Slave driver source code. Nor did I find any SPI Slave driver loaded in the kernel on the TK1 itself.

Is the SPI Slave mode driver available? And has the SPI Slave mode been tested on the Apalis TK1 before?

There is no support for SPI Slave mode in Linux kernel.

The L4T R16.5 kernel sources for T20/T30 did contain such a proprietary SPI slave driver which may be ported to TK1.
