The Cadence I2S Controller implements a function of the multi-channel
(up to 8-channel) bus. Each stereo channel combines functions of a
transmitter and a receiver, and can switch freely between them. Each
channel has independent gating, clock and interruption control. It also
support some of these channels are used as playback and others can also
be used as record in the same time.

Four I2S controllers are used on the StarFive JH8100 SoC. Two of the I2S
controllers use two stereo channels, one of them use four channels, and
one use eight. It had tested on the fpga with WM8960.
