From 1075df4bdeb320bbf94a1f6d3761391264eb2c7f Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Thu, 16 Jun 2022 12:00:45 +0800 Subject: [PATCH] ASoC: fsl-asoc-card: add nau8822 support This is for an imx6sx EVB which has a nau8822 codec connects to the SSI2 interface, so add the nau8822 support in this machine driver. Because the codec driver nau8822.c doesn't handle mclk enabling, here adding a codec_priv->mclk for nau8822 and similar codecs which need to enable the mclk in the machine driver, and enable the mclk in the card_late_probe() conditionally.
