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@xxxxxxxxx. * Replace pci_xxx() APIs with pcim_xxx() APIs. * mirror changes in log printing. v1: * Add support for Loongson I2S controller.
