We need to set a specific bit for 50 bclk rate. So add set_bclk_ratio function to set the bit. Signed-off-by: Bard Liao <bardliao@realtek.com> --- v2: * add define for tdm data format select bit. v3: * change if (ratio == 50) to if ((ratio % 50) == 0) since the bit needs to be set if bclk ratio is divisible by 50. --- sound/soc/codecs/rt5670.c | 19 +++++++++++++++++++ sound/soc/codecs/rt5670.h | 4 ++++ 2 files changed, 23 insertions(+)
