We have a custom board based on imx6sx which originally ran with Linux imx_3.14.28_1.0.0_ga.
Recently I have updated the project to use the imx_4.9.11_1.0.0_ga which also works.
However we would very much like to use a Intel Wireless 9260 module which require a Linux 4.14+ kernel.
I have tried looking into backporting the driver to 4.9 but it did not work.
I have also tried to use the 4.14 kernel from https://github.com/Freescale/linux-fslc but it does not find the PCIE device during boot. It seems to me that the driver for "fsl,imx6sx-pcie" as stated in the device tree cannot be found in the fslc 4.14 kernel so I looked into merging files from the 4.9.11_1.0.0_ga version but there seems to be very large differences between the two kernels making it very cumbersome.
Is there a time frame for release of a newer imx Linux 4.14+ kernel with good imx6sx support which can be used with the Intel 9260 kernel? Or is there something else I could try to get it working?
