Subject: [PATCH v2 1/7] ARM: dts: meson: switch the clock controller to the HHI register area
Date: Fri, 18 Jan 2019 23:52:21 +0100	[thread overview]
Message-ID: <20190118225227.6516-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190118225227.6516-1-martin.blumenstingl@googlemail.com>

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.
