Subject: v2: arm64: dts: sm8150: start populating qups
The QUPs are rather sparse, lets add the zero-th and second qup nodes,
the iommus properties for all of them and the i2c nodes.
With this it's now possible to bringup the touchscreen on my
device, and without crashing!
Derived from OnePlus 7 Pro downstream kernel sources.

Of note, I'm only able to properly test i2c17, as that's what my
touchscreen is attached to. Enabling i2c18 causes my device to lockup
during probe, I suspect those pins are used for some other purpose on my
device.
Changes since v1:
* Pick up Reviewed-By's from Vinod and Bhupesh
* Squash second patch into first
* Add iommus property to dt-binding docs for geni
* Fix i2c19 being mistakenly enabled by default
Caleb Connolly (3):
arm64: dts: qcom: sm8150: add other QUP nodes and iommus
arm64: dts: qcom: sm8150: add i2c nodes
dt-bindings: qcom: geni-se: document iommus

Need to define how many entries (maxItems: 1?)

The property doesn't define the address to be used.
