[PATCH v2 07/18] rockchip: rk3399: Enable random generator on all boards

Jonas Karlman jonas at kwiboo.se
Tue Apr 30 17:30:14 CEST 2024


The RK3399 SoC contain a crypto engine block that can generate random
numbers.

Imply DM_RNG and RNG_ROCKCHIP Kconfig options to take advantage of the
random generator on all RK3399 boards. Also remove the unnecessary use
of a status = "okay" prop.
