crypto: sun8i-ce - Add TRNG clock to the D1 variant
At least the D1 variant requires a separate clock for the TRNG. Without this clock enabled, reading from /dev/hwrng reports: sun8i-ce 3040000.crypto: DMA timeout for TRNG (tm=96) on flow 3 Experimentation shows that the necessary clock is the SoC's internal RC oscillator. This makes sense, as noise from the oscillator can be used as a source of entropy.
