Subject: drm/amdgpu/radeon: Use radeon by default for CIK GPUs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 2b059658d6796a096ef06be9da994d6c44401d5b
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Even if CONFIG_DRM_AMDGPU_CIK is enabled.

There is no feature parity yet for CIK, in particular amdgpu doesn't
support HDMI/DisplayPort audio without DC.

v2:
* Clarify the lack of feature parity being related to HDMI/DP audio.
* Fix "SI" typo in DRM_AMDGPU_CIK help entry.
