Subject: [PATCH v3 1/4] ASoC: fsl_asrc: Change asrc_width to asrc_format
Date: Thu, 27 Feb 2020 10:41:55 +0800 [thread overview]
Message-ID: <ffd5ff2fd0e8ad03a97f6a640630cff767d73fa7.1582770784.git.shengjiu.wang@nxp.com> (raw)

In-Reply-To: <cover.1582770784.git.shengjiu.wang@nxp.com>
asrc_format is more inteligent variable, which is align
with the alsa definition snd_pcm_format_t.
