From a Tegra perspective, given that we don't use SPI in conjunction with the rt5677 codec, only I2C so far, I am not sure we should make the tegra_rt5677 driver dependent upon it. We should be able to operate without the SPI bits enabled. Cheers Jon

Arnd, if you can share the .config that exposes this problem it'd be nice FWIW, there are other missing dependencies, the SPI controller was not explicitly enabled so depending on the Kconfigs used by a distro the machine driver probe could fail with the spi-RT5677AA component never registered.
