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.
