I will rewrite the dependency between the card and the DAI driver, as follows:

config SND_SOC_LOONGSON_CARD
        tristate "Loongson Sound Card Driver"
        depends on LOONGARCH || COMPILE_TEST
        select SND_SOC_LOONGSON_I2S_PCI if PCI
        select SND_SOC_LOONGSON_I2S_PLATFORM if OF

config SND_SOC_LOONGSON_I2S_PCI
        tristate "Loongson I2S-PCI Device Driver"
        select REGMAP_MMIO

config SND_SOC_LOONGSON_I2S_PLATFORM
        tristate "Loongson I2S controller as platform device"
        select REGMAP_MMIO
        select SND_SOC_GENERIC_DMAENGINE_PCM

Thanks.
