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 mfd cells which we hang the i2s codec and DMA engine on. Because of this, this patch set covers two subsystems: drm and alsa. The drm patches add support for 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, I'd like to take the alsa patches in via the drm tree. V2 changes: - Use the MFD subsystem rather than adding our own bus - Squash all sub-feature patches together - fix comments mentioned in previous review V3 changes: - Update the designware driver to handle slave mode, amd specific features - Use the designware driver directly for i2s - Move the DMA handling from the GPU driver into the AMD ASoC driver - Change the license on the ASoC driver to GPL v4 changes: - patch "ASoC : dwc : support dw i2s in slave mode" accepted - Add a _dai_fmt() operation that checks to make sure that the mode we're setting corresponds to what we read back from the hardware. - Split specific quirks into separate patches - Set the specific quirks that apply to AMD chips in the acp driver v5 changes: - patch "ASoC : dwc : add check for master/slave format" accepted - Fix MFD_CORE selection in ACP Kconfig - Add irq domain support to amdgpu driver - Use genirq in ACP DMA driver - Export some genpd symbols to support ACP powergating (Acked by PM maintainer) - Use genpd for ACP powergating - add separate capture and playback instances of dws in ACP init - add runtime suspend support for dws in master mode Patch 9 adds the register headers for the ACP block which is a pretty big patch so I've excluded it from email.
