The intention of this patch series is to enable audio support on FSD SoC.

The following features are added in samsung I2S interface:
1. Add TDM support on samsung I2S interface
2. Allow sound card to directly configure prescaler divider instead of
calculating it from frame clock

Also the sound card support for FSD SoC is added, which utilizes samsung
I2S interface as CPU DAI.

This patch is dependent on fsd-pinctrl fixes patch series [1]
