From: Alexey Romanov <avromanov@xxxxxxxxxxxxxx>

Hello!

This patch series adds hwrng support for Amlogic S4-series.
Now, S4 uses a new random number generation algorithm.
This changes implemnents new algo and also adds description
to meson-s4.dtsi.

V2:

- Use readl_relaxed_poll_timeout_atomic() function instead of loop.
- Use two different functions: meson_rng_read() and meson_s4_rng_read().
- Fix naming in DT schema (meson-s4-hwrng instead of meson-hwrng-s4).
- A little code style fixes.

V3:

- Fix commit message in patch with dt-bindings schema changes.

V4:

- Drop struct meson_rng_priv field from struct meson_rng_data.

Alexey Romanov (3):
drivers: rng: meson: add support for S4
dt-bindings: rng: meson: add meson-rng-s4 compatible
arch/arm64: dts: meson-s4: add hwrng node
