* DOC: IP Blocks
*

* IP blocks provide various functionalities: display, graphics,
* video decode, etc. The IP blocks that comprise a particular GPU
* are listed in the GPU's respective SoC file. amdgpu_device.c

* It can then operate on this list to perform standard driver operations
* such as: init, fini, suspend, resume, etc.
*
*
* IP block implementations are named using the following convention:
* <functionality>_v<version> (E.g.: gfx_v6_0).
