From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
Add nodes to rk356x devicetree to support PCIe v3.
Co-developed-by: Peter Geis <pgwipeout@xxxxxxxxx>
Signed-off-by: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>
---
v3:
- fix from Peter: change bus-range and msi-map, msi-map needs
to start from 0x0
v2:
- change to compatible with soc-part
- change rockchip,bifurcation to vendor unspecific bifurcation
