Confirmed: 35: 83626 0 0 0 gpio-mxc 3 Level pca= 9450-irq and 200: 270180 0 0 0 GICv3 67 Level 30a= 20000.i2c ... 200: 400925 0 0 0 GICv3 67 Level 30a= 20000.i2c ... increasing rapidly on the debix-som. I started out on the linux-media branches which were 7.0-rc2 based, and this didn't happen but cherry-picking in 5d0efaf47ee90 certainly causes this issue to occur on my board. -- Kieran >=20 > > --- > > arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > >=20 > > diff --git a/arch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts b/a= rch/arm64/boot/dts/freescale/imx8mp-debix-model-a.dts > > index 9422beee30b29c5a551b08476c80fbff96af3439..df7489587e48ed0c678f112= 91f6f2b77082ade95 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 > > =20 > > pinctrl_pmic: pmicirqgrp { > > fsl,pins =3D < > > - MX8MP_IOMUXC_GPIO1_IO03__GPIO1_IO03 = 0x41 > > + MX8MP_IOMUXC_GPIO1_IO03__GPIO1_IO03 = 0x000001c0 > > >; > > }; > > =20 > >=20 > > --- > > base-commit: 09c0f7f1bcdbc3c37a5a760cbec76bf18f278406 > > change-id: 20260324-imx8mp-dts-fix-512530fe4dcd >=20 > --=20 > Regards, >=20 > Laurent Pinchart
