Take a look at imx_3.14.38_6ul_ga branch; It does use 22 in the dmas nodes:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/boot/dts/imx6sx.dtsi?h=imx_3.14.38_6ul_ga
However, this list is only about mainline kernel, so please run all
your tests with mainline instead of FSL 3.14.
