Hi there,
we are trying to extend our audio system by daisy chaining two AD1938 audio codecs. From the datasheet I got the information that both codecs are configured equally (512 fs DACs / 256 fs ADCs / single line TDM mode). So, of course, both codecs appear as one codec to the platform DAI. I think it should work, if both codecs are configured equally in series via regmap in the codec driver. For example:
static int ad193x_hw_params(...){
...
regmap_update_bits(ad193x_0->regmap, AD193X_PLL_CLK_CTRL0, AD193X_PLL_INPUT_MASK, master_rate);
regmap_update_bits(ad193x_1->regmap, AD193X_PLL_CLK_CTRL0, AD193X_PLL_INPUT_MASK, master_rate);
...
}
Does anybody know, how to pass two regmap configs to the driver, so that I can configure both codecs in the same way? Or any other idea how to get two daisy chained codecs working with ALSA?
Thanks!
