From b774be9de5db9022a52829b6253d1502fba68c01 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Wed, 25 Aug 2021 11:23:57 -0500 Subject: [PATCH] rockchip: px30: add support for HW RNG for Odroid Go Advance The Odroid Go Advance has a hardware random number generator present. The device does not have an upstream Linux driver, but does have a U-Boot driver. Add the appropriate node so that the hardware RNG can be used in U-Boot.
