2019-11-27ASoC: AMD: Enable clk in startup intead of hw_paramsYu-Hsuan Hsu
Some usages only call startup and shutdown without setting hw_params (e.g. arecord --dump-hw-params). If we don't enable clk in startup, it will cause ref count error because the clk will be disabled in shutdown. For this reason, we should move enabling clk from hw_params to startup. In addition, the hw_params is fixed in this driver(48000 rate, 2 channels, S16_LE format) so we don't need to change the clk rate after the hw_params is set.

2018-12-06ASoC: use dma_ops of parent device for acp_audio_dmaYu Zhao
AMD platform device acp_audio_dma can only be created by parent PCI device driver (drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c). Pass struct device of the parent to snd_pcm_lib_preallocate_pages() so dma_alloc_coherent() can use correct dma_ops. Otherwise, it will use default dma_ops which is nommu_dma_ops on x86_64 even when IOMMU is enabled and set to non passthrough mode. Though platform device inherits some dma related fields during its creation in mfd_add_device(), we can't simply pass its struct device to snd_pcm_lib_preallocate_pages() because dma_ops is not among the inherited fields. Even it were, drivers/iommu/amd_iommu.c would ignore it because get_device_id() doesn't handle platform device. This change shouldn't give us any trouble even struct device of the parent becomes null or represents some non PCI device in the future, because get_dma_ops() correctly handles null struct device or uses the default dma_ops if struct device doesn't have it set.

2018-12-06ASoC: use DMA addr rather than CPU pa for acp_audio_dmaYu Zhao
We shouldn't assume CPU physical address we get from page_to_phys() is same as DMA address we get from dma_alloc_coherent(). On x86_64, we won't run into any problem with the assumption when dma_ops is nommu_dma_ops. However, DMA address is IOVA when IOMMU is enabled. And it's most likely different from CPU physical address when AMD IOMMU is not in passthrough mode. Signed-off-by: Yu Zhao <yuzhao@google.com> Signed-off-by: Mark Brown <broonie@kernel.org>
