From 38592ae6dc9f84b7a994c43de2136b8115ca30f6 Mon Sep 17 00:00:00 2001 From: Vijendar Mukunda Date: Wed, 23 Aug 2023 13:03:39 +0530 Subject: ASoC: SOF: amd: clear dsp to host interrupt status DSP_SW_INTR_STAT_OFFSET is a common interrupt register which will be accessed by both ACP firmware and driver. This register contains register bits corresponds to host to dsp interrupts and vice versa. when dsp to host interrupt is reported, only clear dsp to host interrupt bit in DSP_SW_INTR_STAT_OFFSET.
