Subject: [PATCH v2 8/9] arm64: dts: qcom: x1e80100-dell-latitude-7455:
 Enable IRIS

Enable IRIS to allow using the hardware-accelerated video codecs. The
firmware is not upstream in linux-firmware yet, so users need to copy it
from Windows to qcom/x1e80100/dell/latitude-7455/qcvss8380.mbn (just like
GPU/ADSP/CDSP firmware).
