mSGDMA Linux Device Drivers

Hello,

I would like to make use of the drivers found here: https://github.com/torvalds/linux/blob/master/drivers/dma/altera-msgdma.c

in a user program where data can be transferred from one data structure to another. I have tried adding the mSGDMA to the device tree and it does not seem to work.

msgdma_0: msgdma@0xf9000020 {

compatible = "altr,msgdma-19.1", "altr,msgdma-1.0";

reg = <0x00000020 0x00000020>,

<0x00000040 0x00000010>;

reg-names = "csr", "descriptor_slave";

interrupt-parent = <0x5>;

interrupts = <21>;

}; //end msgdma@0x20 (msgdma_0)

I have went through documentations, device tree generators, etc. and none seem to get the mSGDMA to work with the drivers. Was anyone able to use the drivers? I am working on the Stratix 10 v19.1
