[PATCH 5.1 035/115] ASoC: fsl_asrc: Fix the issue about unsupported rate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: S.j. Wang <shengjiu.wang@xxxxxxx>

commit b06c58c2a1eed571ea2a6640fdb85b7b00196b1e upstream.

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.

Fixes: fff6e03c7b65 ("ASoC: fsl_asrc: add support for 8-30kHz
output sample rate")
