From 37bb773b4a5a5107b92beda3447a7c6c0cfc1237 Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Fri, 6 Feb 2026 09:48:02 +0800 Subject: [PATCH] ASoC: dt-bindings: fsl,imx-asrc: Add support for i.MX952 platform Add new compatible string 'fsl,imx952-asrc' for i.MX952 platform, below are the differences that make this ASRC not fallback compatible with other platforms. 1) There is a power domain on i.MX952 for the wakeupmix system where ASRC is in. But it is enabled by default, ASRC device don't need to enable it, so it is optional for i.MX952. 2) The clock sources of ASRC are different on i.MX952. 3) There is a limitation on i.MX952 that DMA request is not cleared at the end of conversion with dma slave mode. Which causes sample is dropped from the input fifo on the second time if DMA is triggered before the client device and DMA may copy wrong data from output fifo as the output fifo is not ready in the beginning. So there is specially handling in the driver.
