| Subject: [PATCH 0741/1795] ARM: dts: iwg20d-q7-common: Sound DMA support via |
| SRC on DTS |
| |
| DMA transfer to/from SRC |
| |
| DMA DMApp |
| [MEM] -> [SRC] -> [SSIU] -> [SSI] |
| |
| DMA DMApp |
| [MEM] <- [SRC] <- [SSIU] <- [SSI] |
| |
| Current sound driver is supporting SSI/SRC random connection. |
| So, this patch is trying |
| SSI1 -> SRC3 |
| SSI0 <- SRC2 |
