Hi, This patch set implements support for i2s audio and new AMD GPUs. The i2s codec is fed by a DMA engine on the GPU. To handle this we create an amd gnb (graphics northbridge) bus which we can hang the i2s codec on. Because of this, this patch set covers two subsystems: drm and alsa. The drm patches add support for the gnb bus and the ACP hw block which provides the DMA engine for the i2s codec. The alsa patches add the ASoC driver for the i2s codec. Since the alsa changes depend on the drm changes in this patch set as well as some other drm changes queued for 4.3, I'd like to take the alsa patches in via the drm tree. Patch 3 adds the register headers for the ACP block which is a pretty big patch so I've excluded it from email.
