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