The original driver uses "NAU8825" name and the one above is "NAU88L25". Please keep naming consistent. The driver chip should be names either NAU8825 or NAU88L25 but it has to be done everywhere. I had this question to Vinod earlier as well sent NAU88L25 -> NAU8825 rename patch but got no reply. > + depends on X86_INTEL_LPSS && I2C > + select SND_SOC_INTEL_SST > + select SND_SOC_INTEL_SKYLAKE > + select SND_SOC_NAU8825 > + select SND_SOC_MAX98357A > + select SND_SOC_DMIC > + help > + This adds support for ASoC Onboard Codec I2S machine driver.
