This patch was used to add TAS2781 devices on SPI support in sound/pci/hda.
It use ACPI node descript about parameters of TAS2781 on SPI, it like:
    Scope (_SB.PC00.SPI0)
    {
        Device (GSPK)
        {
            Name (_HID, "TXNW2781")  // _HID: Hardware ID
            Method (_CRS, 0, NotSerialized)
            {
                Name (RBUF, ResourceTemplate ()
                {
                    SpiSerialBusV2 (...)
                    SpiSerialBusV2 (...)
                }
            }
        }
    }

And in platform/x86/serial-multi-instantiate.c, those spi devices will be
added into system as a single SPI device, so TAS2781 SPI driver will
probe twice for every single SPI device. And driver will also parser
mono DSP firmware binary and RCA binary for itself.

Hi Pierre,

Do you know any different between windows and Ubuntu on SPI inialyze?
We are testing my patch on Laptop (HP-Varcolac, SSID:103C8B92, fly-out SPI & I2S cables), no any issue with wondows, but with Linux, second speaker has no sound, it's initialyze is totally same with first AMP, and relative registers can be dumped, no problem found.

Best Regards
Jim
