At 192kHz only 128xfs is supported. The existing driver selects - 128xfs automatically for some lower samples rates. By using an additional - mclk_div divider, it is now possible to control the behaviour. This allows - using 256xfs PLL frequency on all sample rates up to 96kHz. It should allow - lower jitter and better signal quality. The behavior has to be controlled by - the sound card driver, because some sample frequency share the same setting. - e.g. 192kHz and 96kHz use 24.576MHz master clock. The only difference is the - MCLK divider. - -This also added support for 32bit data. - -Signed-off-by: Daniel Matuschek <daniel@matuschek.net> ---- - sound/soc/codecs/wm8804.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - ---- a/sound/soc/codecs/wm8804.c -+++ b/sound/soc/codecs/wm8804.c -@@ -304,6 +304,7 @@ static int wm8804_hw_params(struct snd_p - blen = 0x1; - break; - case 24: -+ case 32: - blen = 0x2; - break; - default: -@@ -515,7 +516,7 @@ static const struct snd_soc_dai_ops wm88 - }; - - #define WM8804_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S20_3LE | \ -- SNDRV_PCM_FMTBIT_S24_LE) -+ SNDRV_PCM_FMTBIT_S24_3LE | SNDRV_PCM_FMTBIT_S32_LE) - - #define WM8804_RATES (SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \ - SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_64000 | \ |
