From 6b3fff78c13f1a2ba5a355a101fa1ca0a13054ad Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Thu, 24 Jul 2025 10:38:59 +0200 Subject: [PATCH] arm64: dts: mediatek: mt7986a: Fix PCI-Express T-PHY node address The PCIe TPHY is under the soc bus, which provides MMIO, and all nodes under that must use the bus, otherwise those would clearly be out of place. Add ranges to the PCIe tphy and assign the address to the main node to silence a dtbs_check warning, and fix the children to use the MMIO range of t-phy.
