From b06c58c2a1eed571ea2a6640fdb85b7b00196b1e Mon Sep 17 00:00:00 2001 From: "S.j. Wang" Date: Wed, 15 May 2019 06:42:18 +0000 Subject: ASoC: fsl_asrc: Fix the issue about unsupported rate When the output sample rate is [8kHz, 30kHz], the limitation of the supported ratio range is [1/24, 8]. In the driver we use (8kHz, 30kHz) instead of [8kHz, 30kHz]. So this patch is to fix this issue and the potential rounding issue with divider.
