[PATCH v4 1/4] arm64: dts: ti: k3-j784s4-main: Add PCIe nodes

From: Siddharth Vadapalli
Date: Wed May 29 2024 - 04:27:07 EST

TI's J784S4 SoC has four instances of Gen3 PCIe Controllers namely
PCIe0, PCIe1, PCIe2 and PCIe3. PCIe0 and PCIe1 are 4-Lane controllers
while PCIe2 and PCIe3 are 2-Lane controllers.

Add support for the Root Complex Mode of operation of these PCIe instances.

v3:
https://lore.kernel.org/r/20240523111008.4057988-2-s-vadapalli@xxxxxx/
Changes since v3:
- Added ranges for PCIe2 and PCIe3 in k3-j784s4.dtsi which was missed in
v3 series.
