[PATCH v2 2/3] ARM: dts: imx6: phycore-som: Increase PMIC max SOC and ARM voltage

From: Primoz Fiser

Date: Thu Oct 01 2026 - 03:10:38 EST


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).
