Sounds reasonable. I will change the commit message to refer to i.MX6UL/ULL/SX. Actually one of our customers has a dts for i.MX6UL, that enables the DMA for UART6. The DMA not being enabled in imx6ul.dtsi doesn't mean no one is using it. Actually I have no idea why it's enabled by default for i.MX6SX and disabled by default for i.MX6UL.
