D1 has a crypto engine similar to the one in other Allwinner SoCs. Like H6, it has a separate MBUS clock gate. It also requires the internal RC oscillator to be enabled for the TRNG to return data, presumably because noise from the oscillator is used as an entropy source. This is likely the case for earlier variants as well, but it really only matters for H616 and newer SoCs, as H6 provides no way to disable the internal oscillator. Signed-off-by: Samuel Holland <samuel@sholland.org> --- I noticed that the vendor driver has code to explicitly enable IOSC when using the TRNG on A83T (search SS_TRNG_OSC_ADDR), but that is covered by a different binding/driver in mainline.

This doesn't have an ack from Rob Herring. Would you like me to apply just the crypto patch by itself?
