i.MX6 and EIM interface to XR16V798

I'm trying to integrate the EXAR XR16V798 serial port extender to the i.MX6dl through the EIM bus. It is set up with CS0, DA0-7 and D0-7. However, I'm struggling to understand how it should be set up in the devicetree. Examples I've seen are most on integrating SRAM or similar. Default my EIM bus is set up as this:


weim: weim@021b8000 {
compatible = "fsl,imx6q-weim";
reg = <0x021b8000 0x4000>;
interrupts = <0 14 0x04>;
clocks = <&clks 196>;


Does anyone have any information to nudge me in the right direction?


Best regards,
