I think the same is needed for imx8mp-debix-som-a.dtsi, but I can't confirm it as I don't have the schematics for the SoM, neither do I have access to the board. Dan, Kieran, Stefan, could one of you check if you get an interrupt storm from the PMIC on v7.0 ? > --- > arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts b/arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts > index 9422beee30b29c5a551b08476c80fbff96af3439..df7489587e48ed0c678f11291f6f2b77082ade95 100644 > --- a/arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts > +++ b/arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts > @@ -440,7 +440,7 @@ MX8MP_IOMUXC_SAI5_RXC__I2C6_SDA 0x400001c3 > > pinctrl_pmic: pmicirqgrp { > fsl,pins = < > - MX8MP_IOMUXC_GPIO1_IO03__GPIO1_IO03 0x41 > + MX8MP_IOMUXC_GPIO1_IO03__GPIO1_IO03 0x000001c0 > >; > }; > > > --- > base-commit: 09c0f7f1bcdbc3c37a5a760cbec76bf18f278406 > change-id: 20260324-imx8mp-dts-fix-512530fe4dcd -- Regards, Laurent Pinchart
