[PATCH 1/3] dt-bindings: input: syna,rmi4: Allow 'panel' property

[Konrad Dybcio]

From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

Many RMI4 implementations are present in in-cell panels where the
precise power seqeuencing is paramount to both the display and the
touch parts to function properly.

Allow binding to a panel node, which is expected to handle that.
