1 Renesas R-Car sound
7 Renesas R-Car and RZ/G sound is constructed from below modules
11 - SRC : Sampling Rate Converter
12 - CMD
13 - CTU : Channel Transfer Unit
14 - MIX : Mixer
15 - DVC : Digital Volume and Mute Function
22 * Multi channel
25 Multi channel is supported by Multi-SSI, or TDM-SSI.
27 Multi-SSI : 6ch case, you can use stereo x 3 SSI
28 TDM-SSI : 6ch case, you can use TDM
34 See datasheet to check SRC/CTU/MIX/DVC connect-limitation.
36 ${LINUX}/arch/arm/boot/dts/r8a7790-lager.dts can be good example.
39 Playback: [MEM] -> [SRC2] -> [DVC0] -> [SSIU0/SSI0] -> [codec]
40 Capture: [MEM] <- [DVC1] <- [SRC3] <- [SSIU1/SSI1] <- [codec]
63 ------> [SRC] ------>
74 ------------------
76 ------------------
78 You need to use "simple-scu-audio-card" or "audio-graph-scu-card" for it.
81 ------------------
83 ------------------
91 * CTU (Channel Transfer Unit)
95 ------> [CTU] -------->
97 CTU can convert [xx]ch to [yy]ch, or exchange outputed channel.

150 [MEM] -> [SRC2] -> [CTU03] -+
186 In DMA mode, you can select not to use SSIU by using "no-busif" via SSI.
189 This driver is assuming that audio-graph card will be used.

242 ** Multi-SSI
244 You can use Multi-SSI.

249 ** TDM-SSI
253 Driver can automatically switches TDM <-> stereo mode in this case.
