The PCM1795 is register compatible with the PCM1792A, but it encodes two of the register 18 FMT[2:0] values differently, so the format encoding is described with a per-codec table instead of the width switches. Only the PCM1795 has real 32-bit formats; on the PCM1792A and the PCM1796 a 32-bit container keeps the 24-bit code, as it always has. Left-justified, which the driver accepted but never programmed, is added on the way.
