I would suggest to leave the CTS_N_K to the current setting (3), unless
we can change the CTS_N_K on the fly according to the used sample format.
Yes, this is possible:
- the tda998x codec may call the tda998x hdmi in the hw_params()
function, i.e. when the sample format is known, and then,
- the tda998x_audio_update() function may have the audio parameters
(struct snd_pcm_hw_params) as an argument, and CTS_N_K may be set
to either 1, 2 or 3 for SNDRV_PCM_FORMAT_S16_LE / S24_LE and S32_LE.
This is working in my machine. Would it also work for you?
I am having trouble getting the tda998x-codec working on BBB. The
problem is I do not have a DT node for the tda998x driver. Instead I
have tilcdc-slave node that provides pdata for the tda-driver.
I am thinking of solving the problem by adding a reference to the
i2c-adapter hosting tda998x as an optional DT property to the codec
node. I could then dig the driver instance from the i2c adapter's
children. Any better ideas?
Best regards,
Jyri
