+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.
