Add UART routing driver and the device tree nodes.
v3:
- Add individual bindings in YAML
- Add support for AST24xx (AST25xx shares the same design)
- Add more explanation for the sysfs ABI
v2:
- Add dt-bindings
- Add ABI documents for the exported sysfs interface
- Revise driver implementation suggested by Joel
Chia-Wei Wang (3):
dt-bindings: aspeed: Add UART routing controller
soc: aspeed: Add UART routing support
ARM: dts: aspeed: Add uart routing to device tree
