This adds support for the TRNG found in the RK3588 SoC to the rockchip_rng driver so that it can be used for things such as seeding randomness to Linux. Changes in V3: - Moved notes from commit to cover letter. - Added Reviewed-By tag. Changes in V2: - Modified Kconfig to note that the Rockchip RNG driver supports all versions of the hardware (v1, v2, and the trng in the rk3588).
