- /* I2S2 function select */
- SOC_SINGLE("I2S2 Func Switch", RT5645_GPIO_CTRL1, RT5645_I2S2_SEL_SFT,
1, 1),What functions is this switching?
It is the pin share switch. The I2S data pins are the pin share to GPIO3/4/5/6. If we want to use the GPIO3/4/5/6, we need to set it. We will modify it using the platform data to set it.

These look like they should be part of DAPM, they're about routing data as far as I can tell.
These are the data related controls with TDM function, not related the routing path. For instance, it likes the L and R channel data swap, or copy function.
