Commit6c42db30d8introduced audio support based on alsa ucm profiles taken from the ChromeOS userspace. Both in the kernel as well as alsa they were named (and matched against) ROCKCHIP-I2S. Audio profiles are very much board-specific and hogging the ROCKCHIP-I2S name would make it harder for future boards and also is misleading. For Veyron boards the audio setup is similar over all variants, so VEYRON-I2S is a more suitable name. This rename also was merged into the alsa ucm profile so both userspace and kernel match and the old naming was never released in any alsa or kernel release.
