Subject: [PATCH 1/3] ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage
Date: Fri, 29 Nov 2019 17:48:57 +0100	[thread overview]
Message-ID: <20191129164859.15632-1-m.felsch@pengutronix.de> (raw)

The current set minimum voltage of 730000mV seems to be wrong. I don't
know the document which specifies that but the imx6qdl datasheets says
that the minimum voltage should be 1.05V for VDD_ARM (LDO enabled, lowest
opp) and 1.275V for VDD_SOC (LDO enabled, lowest opp).

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