[alsa-devel] [PATCH 3/3] sound/soc/lapis: add platform driver

Searching git log,
tegra_i2s.c seems modern.
I have a question.

According to platfom.txt, describes like below.
struct snd_soc_ops {

On the other hand, tegra_i2s.c describes like below.

static const struct snd_soc_dai_ops tegra_i2s_dai_ops = {

Which is true as modern driver ? or case by case ?

>> +#define      I2S_CH0_MCLK            (12288000) /* Master Clock Frequency[Hz] */
> This looks like it should be board specific?
Should our platform driver use "clk_get()" ?
If no, how should our driver get the value ?

thanks in advance.
