| 4 | Subject: [PATCH] ASoC: fsl_(e)sai: introduce "shared-interrupt" DT flag (part |
| 5 | 2) |
| 6 | |
| 7 | SAI & ESAI interfaces may share the same interrupt with EDMA, |
| 8 | so that we need a flag to trigger proper shared interrupt |
| 9 | handling. For compatibility the same DT flag, "shared-interrupt", |
| 10 | is introduced as the one used in drivers/dma/fsl-edma-v3.c. |
