2017-04-04drm/amdgpu: Read vram width from integrated system info tableHarry Wentland4-82/+123
On KB, KV, CZ we should read the vram width from integrated system table, if we can. The NOOFCHAN in MC_SHARED_CHMAP is not accurate. With this change we can enable two 4k displays on CZ again. This use case was broken sometime in January when we started looking at vram_width for bandwidth calculations instead of hardcoding this value. v2: Return 0 if integrated system info table is not available.

While it is possible to hook other CRTC implementations into imx-drm in practice there are none yet and the option to disable ipuv3-crtc support has been hidden for a long time.

Cleanup overly complex omap_modeset_init(). The function is trying to support many unusual configuration, that have never been tested and are not supported by other parts of the dirver. After cleanup the init function creates exactly one connector, encoder, crtc, and primary plane per each connected dss-device. Each connector->encoder->crtc chain is expected to be separate and each crtc is connect to a single dss-channel. If the configuration does not match the expectations or exceeds the available resources, the configuration is rejected.
