Correct.

This is a custom NXP driver.

I suggest you use the standard driver provided by the mainline kernel.

imx6qdl-sabresd has camera supported:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/=
arm/boot/dts/imx6qdl-sabresd.dtsi?h=3Dv6.1.46#n318

Here is the documentation for it:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Docum=
entation/admin-guide/media/imx.rst?h=3Dv6.1.46

Hope this helps.
