imx95 jailhouse iommu configuration

Hi,

Is it possible to configure the IOMMU for i.MX95 on Jailhouse?

I'm comparing https://github.com/nxp-imx/imx-jailhouse/blob/lf-6.18.20_2.0.0/configs/arm64/imx8qm.c with https://github.com/nxp-imx/imx-jailhouse/blob/lf-6.18.20_2.0.0/configs/arm64/imx95.c and latter does not have any .iommu_units defined. Is this an oversight or is this not possible with i.MX95? From my understanding i.MX95 supports the newer SMMUv3, I would expect something like this in the root cell file:

.iommu_units= {
{
.type = JAILHOUSE_IOMMU_SMMUV3,
.base = 0x36600000,
.size = 0x100000,
},
}

Thanks.
