Subject: [PATCH 0/2] ASoC: spacemit: add i2s support to K1 SoC

On the K1 SoC, there is a full-duplex I2S controller.

The I2S is programmable, with the sample width configurable
to 8, 16, 18, or 32 bits.

A dedicated FIFO is provided for transmit (TXFIFO) and another
for receive (RXFIFO). In non-packed mode, both FIFOs are 32
entries deep and 32 bits wide, giving a total of 32 samples each.

The register definitions can be found here[1]
