[PATCH v2] dt-bindings: PCI: mediatek-gen3: Add support for MT8188 and MT8195

From: Jianjun Wang
Date: Thu Jul 28 2022 - 23:33:51 EST


MT8188 and MT8195 are ARM platform SoCs with the same PCIe IP as MT8192.

Also add new clock name "peri_mem" since the MT8188 and MT8195 use clock
"peri_mem" instead of "top_133m".
