ASoC: SAMSUNG: 24-bit audio playback on Exynos4210
Using 256fs or 512fs will result in distortion of 24-bit audio samples. This is because the lrclk generated is not proper. Using 384 fs generates proper output. Signed-off-by: Giridhar Maruthy <giridhar.maruthy@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
