From 6cd249cfad68a231336983e2216d75b3ddfde1d6 Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih Date: Mon, 8 Jul 2019 22:19:01 +0800 Subject: ASoC: max98357a: use mdelay for sdmode-delay max98357a_daiops_trigger() is possible to be called in atomic context if the .nonatomic flag is equal to 0 in the DAI links. When cancel_delayed_work_sync() in max98357a_daiops_trigger() is called in atomic context, kernel emits the following message: "BUG: sleeping function called from invalid context". According to the DT binding document, value less than or equal to 5ms of sdmod-delay should be sufficient to avoid the pop noise. Use mdelay (i.e. busy loop) for such low delay should be acceptable.

For example, sysclk = 24.576MHz, TX rate = 96000Hz, RX rate = 48000Hz. Then ratio of TX = 256, ratio of RX = 512, For MFreq is shared by TX and RX instance, the correct value of MFreq is 2 for both TX and RX. But original method will cause MFreq = 0 for TX, MFreq = 2 for RX. If TX is started after RX, RX will be impacted, RX work abnormal with MFreq = 0. This patch is to select proper MFreq value according to TX rate and RX rate.
