From aa836152420af94d014ddd677a5f95544abef4f6 Mon Sep 17 00:00:00 2001 From: Vijendar Mukunda Date: Wed, 23 Aug 2023 13:03:33 +0530 Subject: [PATCH] ASoC: SOF: amd: remove unused sha dma interrupt code During initial development time for RN platform, when SHA dma gets completed, SHA DMA engine used to raise the ACP interrupt. In ACP interrupt handler, SHA DMA interrupt got handled. Currently SHA DMA compleition is verified by checking transfer count using read poll time out logic. Remove unused SHA dma interrupt handling code.
