i.MX 8QXP boards feature an Hifi4 DSP from Tensilica. This patch series aims on adding the DT node describing the DSP, but it also contains the Linux SOF DSP driver code that will use the DT node for easier review. Note that we switched to the new yaml format for bindings documentation. The DSP will run SOF Firmware [1]. Patches 1,2,3 are adding support for Linux DSP driver are already sent for review to SOF folks [2] Ideally, patches 4/5 and 5/5 will go upstream through Shawn's tree while 1-3/5 will go upstream via Pierre's tree -> ASoC tree. Mind that SOF DSP support depends on IMX DSP communication protocol up for review here: https://lkml.org/lkml/2019/8/1/260 Shawn, can you pick this up first? Symbol dependencies are hopefully set correct so even if one of the patches is not in a tree the compilation will not fail because the symbols depending on that patches will not be selected.
