This patch is based on Linux 4.1-rc1 and Sascha's SCPSYS power patch [1]. The AFE unit comprises several memory interfaces that communicate with CPU, a multi input multi output digital audio interconnect, and several external interfaces (e.g. I2S). [1] https://lkml.org/lkml/2015/6/9/172 changes since RFC: - Use DPCM to model AFE AFE memory interfaces such as DL1, VUL are modeled as frontend DAIs, and AFE IOs such as I2S, HDMI are backend DAIs. Which memif and IO to be used can be set in the machine driver. There is no need to indicate this in dts anymore so include/dt-bindings/sound/mtk-afe.h is removed. AFE connections are represented by DAPM widgets and routes, and set connection APIs/tables are no longer required. (mtk-afe-connection.c and mtk-afe-connection.h are removed) Instead, mixer controls are used to do connection/disconnection. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
