Hi all,

This patchset adds support for Loongson I2S controller, and
introduce a ASoC machine driver for loongson platform.

The Loongson I2S controller is available on Loongson
7a2000/2k2000 chips, works as a PCI device. It has two
private DMA controllers used to playback and capture.
Each DMA controller has one channel.

The ASoC machine driver adds support for audio device which
using loongson I2S controller to tranfser the audio data.
The audio device uses "PRP0001" as its ACPI device ID, which
provides a means to use the existing DT-compatible device
identification in ACPI.


Thanks.

v2:
* Use ACPI bindings to reference I2S and codec nodes.
* Add 'required' restriction for sound-dai property in
  dt-bindings.
* Fix build errors from lkp@intel.com.
* Replace pci_xxx() APIs with pcim_xxx() APIs.
* mirror changes in log printing.

v1:
* Add support for Loongson I2S controller.
