From b6db3936f2833c9f27aa9d868bb7bb6e87401b40 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Fri, 18 Jan 2019 23:52:21 +0100 Subject: [PATCH] ARM: dts: meson: switch the clock controller to the HHI register area The clock controller on Meson8/Meson8m2 and Meson8b is part of a register region called "HHI". This register area contains more functionality than just a clock controller: - the clock controller - some reset controller bits - temperature sensor calibration data (on Meson8b and Meson8m2 only) - HDMI controller Allow access to this HHI register area as "system controller". Also migrate the Meson8 and Meson8b clock controllers to this new node.
