In this mode only the following rates can be supported: 256*Fs, 384*Fs, 512*Fs. Improve the error message to give a better indication as to why the clocking failed for slave mode: [ 12.515399] sgtl5000 1-000a: PLL not supported in slave mode [ 12.524124] sgtl5000 1-000a: 233 ratio is not supported. SYS_MCLK needs to be 256, 384 or 512 * fs [ 12.535938] sgtl5000 1-000a: ASoC: can't set sgtl5000 hw params: -22 Signed-off-by: Fabio Estevam Signed-off-by: Mark Brown --- diff --git a/sound/soc/codecs/sgtl5000.c b/sound/soc/codecs/sgtl5000.c index e997d271728d..7ef2687b396f 100644 --- a/sound/soc/codecs/sgtl5000.c +++ b/sound/soc/codecs/sgtl5000.c @@ -626,6 +626,9 @@ static int sgtl5000_set_clock(struct snd_soc_codec *codec, int frame_rate) } else { dev_err(codec->dev, "PLL not supported in slave mode\n"); + dev_err(codec->dev, "%d ratio is not supported.
