Forgot to mention: These last 8 registers (0x20) are a guess, untested.
@Realtek: Can someone please check whether RTD1395 has the same nine sem
registers as RTD1295?

Similarly, this series is lacking a patch for RTD1619 because - same as
for RTD1295/RTD1395 - BSP DT only shows the first one (cf. coverletter).
Same issue for RTD1319 while at it.

Thanks,
Andreas
