Subject: [PATCH 5.5 26/30] ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage
Date: Wed,  1 Apr 2020 18:17:30 +0200	[thread overview]
Message-ID: <20200401161433.901882726@linuxfoundation.org> (raw)
In-Reply-To: <20200401161414.345528747@linuxfoundation.org>

From: Marco Felsch <m.felsch@pengutronix.de>

commit 636b45b8efa91db05553840b6c0120d6fa6b94fa upstream.

The current set minimum voltage of 730000µV seems to be wrong. I don't
know the document which specifies that but the imx6qdl datasheets says
that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed,
lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).

Fixes: ddec5d1c0047 ("ARM: dts: imx6: Add initial support for phyCORE-i.MX 6 SOM")
