This patch adds MIX (Mixer) initial support for rsnd driver. It is assuming that this MIX is used via DPCM. This is sample code for playback. CPU0 : [MEM] -> [SRC1] -> [CTU02] -+ | +-> [MIX0] -> [DVC0] -> [SSI0] | CPU1 : [MEM] -> [SRC2] -> [CTU03] -+ sound { compatible = "renesas,rsrc-card"; ... cpu@0 { sound-dai = <&rcar_sound 0>; }; cpu@1 { sound-dai = <&rcar_sound 1>; }; codec { ... }; }; rcar_sound { ... rcar_sound,dai { dai0 { playback = <&src1 &ctu02 &mix0 &dvc0 &ssi0>; }; dai1 { playback = <&src2 &ctu03 &mix0 &dvc0 &ssi0>; }; }; }; Signed-off-by:Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by:

This patch adds CTU (Channel Transfer Unit) support for rsnd driver. But, it does nothing to data at this point, but is required for MIX support. CTU design is a little different from other IPs (CTU0 is including CTU00 - CTU03, and CTU1 is including CTU10 - CTU13, these have different register mapping) We need to care about it on this driver.

Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri are used from SSI/SSIU/SRC/DVC. But we will add CTU/MIX to this driver. Then, current DMA path searching method is not understandable, and good enough for this purpose. This patch update DMA path search method, more simply. Signed-off-by:

Sometimes we would like to get each module directly, especially data path searching. this patch adds rsnd_io_to_mod() macro, and existing rsnd_io_to_mod_xxx() use it. Signed-off-by:

Current rsnd driver is using Audio DMAC (via DMAEngine) and Audio DMAC peri peri (via original method), and usage of these DMAC are different. Indicates its naming is useful for debugging. Signed-off-by:

Sound L/R order of SSI is different from Linux sound data order. So current rsnd driver is using DALIGN (= data align) to exchange data align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted sound volume will be exchanged if user used volume control on DVC. Because SSIU which exchanges data align is located after DVC. MEM -> SRC -> DVC -> SSI This patch exchanges data align SRC if possible Signed-off-by:

Current rsnd driver has rsnd_get_adinr_bit() to get bit settings for ADINR (= Audio Information Register) of SSIU/SRC/DVC. This patch adds rsnd_get_adinr_chan() to get channel settings for ADINR (= Audio Information Register) of CTU/MIX. Signed-off-by:

Renesas sound IP (= SSIU/SRC/CTU/MIX/DVC) have ADINR (= Audio Information Register), but some of them (= SSIU/SRC/DVC) are for audio data bits, some of them (= CTU/MIX) are for audio data channels. Current rsnd driver is supporting SSIU/SRC/DVC, and these ADINR were for bits. This patch rename rsnd_get_adinr() to rsnd_get_adinr_bit(), and we will have rsnd_get_adinr_chan() for CTU/MIX.

Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC, and these have similar register. xxxIR (Initialization Register) is one of them. These xxxIR need be set to 1 during initialization. Current rsnd driver has src.c / dvc.c, and we will have mix.c. It is readable if these have same named function. This patch adds rsnd_src_initialize_lock/unlock() and make sure it Signed-off-by:

Current sound data route settings is done in dvc.c, and it doesn't care about CTU/MIX at this poinnt, but we need to care about these. OTOH, rsnd driver already has rsnd_path_xxx() functions for data path which are good match for CTU/MIX/DVC path selectio. This patch adds new rsnd_path_parse() to select sound data route which will care about CTU/MIX/DVC path. Signed-off-by:
