[PATCH v3 5/8] dt-bindings: PCI: qcom-ep: add SAR2130P compatible

From: Dmitry Baryshkov
Date: Fri Feb 21 2025 - 10:58:26 EST


Add support for using the PCI controller in the endpoint mode on the
SAR2130P platform. It is impossible to use fallback compatible to any
other platform since SAR2130P uses slightly different set of clocks.
