From 7511009a7642ec86aac192d97623a415abbd3678 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Thu, 13 Jul 2017 13:42:42 +0300 Subject: MLK-15937-4: ASoC: fsl_spdif: Use DMA workaround for SPDIF Similar with commit 2f756e7aa88407 ("MLK-15004-4: ASoC: fsl_esai: esai workaround for imx8qxp Rev1") this is needed because of a hardware issue where SPDIF DMA request signal is active low but the DMA input is active high. The workaround uses GPT to convert DMA request signal to EDMA.
