What are the values? Why this is uint8?
These represents number of fast training sequence and doesn't have
any units and the maximum value for this is 0xFF only so we used
uint8.
You described the desired Linux feature or behavior, not the actual
hardware. The bindings are about the latter, so instead you need to
rephrase the property and its description to match actual hardware
capabilities/features/configuration etc.

Why do you have entire if? You do not have multiple variants, drop.
The child nodes also referencing the qcom,qps615.yaml# node, I tried
to use this way to say "the below properties are for the required for
parent and optional for child".
I don't understand how child device can be exactly the same as parent
device. How does it look in terms of hardware? Pins and supplies?

Nope, drop pattern Properties or explain what is this.
the child nodes represent the downstream ports of the PCIe
switch which wants to use same properties that is why
I tried to use this pattern properties.
Downstream port is not the same as device. Why downstream port has the
same supplies? To which pins are they connected?
Hi Krzysztof,
Downstream ports dosen't have pins or supplies to power on.
But there are properties like qcom,l0s-entry-delay-ns,
qcom,l1-entry-delay-ns, qcom,tx-amplitude-millivolt etc which
applicable for child nodes also. Instead of re-declaring the
these properties again I tried to use pattern properties.
