Add basic dts files for hi3798cv200-poplar board. Poplar is the
first development board compliant with the 96Boards Enterprise
Edition TV Platform specification. The board features the
Hi3798CV200 with an integrated quad-core 64-bit ARM Cortex A53
processor and high performance Mali T720 GPU.

The compatible string here should contain "syscon". It should be
			compatible = "hisilicon,hi3798cv200-crg", "syscon", "simple-mfd";

Here should be #reset-cells.

Thanks for this patch! Some comments below. Do you have instructions for
how to test? In my tries I so far only got resets like for example:

Does U-Boot need to be updated for this to work?

Shouldn't this rather be "tocoding,poplar", "hisilicon,hi3798cv200"?

linux-next.git already has Hi3660 here, so you'll need to rebase.

Also, theoretically bindings documentation should be in a separate,
preceding patch.

Please leave spaces inside the comments for readability.

Are you sure about the size of the second region? And are there really
only two, not four? (1k, 2k, 2k, 2k elsewhere [0])
