From a22b10e2c273308f547c5ad96e3820f312058ae7 Mon Sep 17 00:00:00 2001 From: Viorel Suman Date: Sun, 30 Apr 2017 12:41:33 +0300 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.
