[PATCH v11 3/6] dt-bindings: pci: qcom: Add OPP table

From: Krishna chaitanya chundru
Date: Tue Apr 23 2024 - 05:09:29 EST


PCIe needs to choose the appropriate performance state of RPMh power
domain based on the PCIe gen speed.

Adding the Operating Performance Points table allows to adjust power
domain performance state and ICC peak bw, depending on the PCIe data
rate and link width.
