From a35910d3994a6d1f59b140dea6b00b8a7b134878 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Thu, 15 Jun 2017 23:33:49 +0200 Subject: ARM: dts: meson: add the hardware random number generator All supported Meson SoCs have a random number generator in CBUS. Newer SoCs (GXBB, GXL and GXM) provide only one 32-bit random number register, whereas the older SoCs (Meson6, Meson8 and Meson8b) have two 32-bit random number registers. The existing meson-rng driver only supports the lower 32-bit - but it still works fine on the older SoCs apart from this small limitation.
