Subject: [PATCH v5 -next 10/11] arm64: dts: broadcom: bcm2712: Add PCIe DT nodes
Add PCIe devicetree nodes, plus needed reset and mip MSI-X
controllers.
Signed-off-by: Stanimir Varbanov <svarbanov@...e.de>
---
v4 -> v5:
- Reorder reset-names.
- Dropped bus-range property.
- Added MIP0(pcie2) and MIP1(pcie1) dma-ranges properties to access MIP MSI-X
interrupt controllers.
