Subject: [PATCH v2 0/9] arm64: dts: qcom: x1e80100: Add IRIS video codec

Add the necessary definitions to enable the IRIS video codec for
accelerated video decoding on the X1E CRD, Lenovo ThinkPad T14s, Lenovo
Yoga Slim 7x, Dell Inspiron 14 Plus 7441, Dell Latitude 7455 and Dell XPS
13 9345. The additions are largely copied as-is from sm8550.dtsi with some
minor changes necessary for X1E.

The PAS interface used to boot the IRIS firmware works only when running
the usual setup with the Gunyah hypervisor in EL2 and Linux in EL1. It does
not work when booting Linux/KVM in EL2. The code to start it without using
PAS exists already in the Venus driver, but was not ported over to IRIS
yet. Discussions how to model the video-firmware IOMMU are still ongoing,
so disable IRIS in x1-el2.dtso for now to avoid regressions when running
with KVM.
