Subject: [PATCH 2/4] ARM: dts: imx6: phycore-som: Increase PMIC max SOC and ARM voltage
Date: Wed, 30 Sep 2026 12:25:30 +0200	[thread overview]
Message-ID: <20260930102532.2262700-3-primoz.fiser@norik.com> (raw)
In-Reply-To: <20260930102532.2262700-1-primoz.fiser@norik.com>

The i.MX 6Quad with 1.2 GHz needs 1.4-1.5 V supply voltage for the 1.2
GHz operating point. Therefore this patch increases the maximum output
voltage of the PMIC's SOC and ARM core supply regulators to 1.5 V.
Otherwise transition to 1.2 GHz OPP fails (with the 125 mV anatop LDO
dropout taken into account).
