Hi Syrus,

As I replied earlier, anything older than 5.4 has pretty much no
chance of getting the kernel backports.

If you are specifically working on Ingenic's own SoC support,
I do think that you are in luck as these seem to be fairly well
supported in recent kernels, based on the work that Paul Cercueil
has done over the years, at least for the chips that ended up
in popular development boards and gaming handhelds (jz4725,
jz4740, jz4760, jz4770).

If there are specific drivers that are not yet supported upstream
but work on the patched 3.10 kernel, I'm sure you can find
consulting companies that are able to port those drivers as well.
