Hello.
I would like to use QorIQ LS1021A processor as a SPI slave in Yocto.
My problem is similar to How to design a SPI Slave driver of Linux kernel 2.6.35 on i.MX28 platform, but with other processor.
Thank you in advanced.

Hello Jesus Gutierrez,
Currently, there is no platform to test slave driver. Our software team cannot take on to develop the code. Having said that, our software team just finished the SPI master mode for SPI. You can reference it if you like. I enclosed the patch for linux 4.14.
Thanks,
Yiping
Hello again Yiping,
Thanks you for your reply, and sorry for the Subject of the Question. By mistake, I wrote 2.14 instead of 4.14.
I explain you my context. We are using QorIQ LS1021A processor, in specific we use TQMLS1021xA board. For yocto project we use a BSP layer provided by TQ (https://github.com/tq-systems/meta-tq.git). Our kernel is 4.14.78-TQMLS102xA.BSP.SW.0110. Sorry for the confusion.
We have tested the SPI master mode successfully but we have not get SPI slave mode working. And we wonder if it is possible actually.
Thanks vey much
