Subject: [PATCH v3 5/7] arm64: dts: allwinner: h6: Enable CPU opp tables for Tanix TX6
Date: Sun, 19 Apr 2020 15:50:09 +0200	[thread overview]
Message-ID: <20200419135011.18010-6-peron.clem@gmail.com> (raw)
In-Reply-To: <20200419135011.18010-1-peron.clem@gmail.com>

Enable CPU opp tables for Tanix TX6.

Also add the fixed regulator that provided vdd-cpu-gpu required for
CPU opp tables.

This voltage has been found using a voltmeter and could be wrong.
