Subject: [PATCH 5/7] ARM: dts: sun8i-a33-olinuxino: add cpu-supply
Date: Tue, 20 Dec 2016 11:27:07 +0100	[thread overview]
Message-ID: <20161220102709.9504-6-quentin.schulz@free-electrons.com> (raw)
In-Reply-To: <20161220102709.9504-1-quentin.schulz@free-electrons.com>

This adds the cpu-supply DT property to the cpu0 DT node needed by
the board to adapt the regulator voltage depending on the currently use
OPP.

Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com>

This hasn't been tested on the board but it is what I understand from the
schematics[1] of the board.

Stefan (or anyone owning this board), could you test this series of patch on the
Olinuxino A33, test CPUfreq on it and tell us if it works? Thanks!
