57* DOC: IP Blocks
58*
59* GPUs are composed of IP (intellectual property) blocks. These
60* IP blocks provide various functionalities: display, graphics,
61* video decode, etc. The IP blocks that comprise a particular GPU
62* are listed in the GPU's respective SoC file. amdgpu_device.c
63* acquires the list of IP blocks for the GPU in use on initialization.
64* It can then operate on this list to perform standard driver operations
65* such as: init, fini, suspend, resume, etc.
66*
67*
68* IP block implementations are named using the following convention:
69* <functionality>_v<version> (E.g.: gfx_v6_0).
