[PATCH v7 0/5] arm: aspeed: Add UART routing support

From: Chia-Wei Wang
Date: Sun Sep 26 2021 - 22:31:46 EST


Add UART routing driver and the device tree nodes.

v7:
- Drop unused 'reg-io-width' properties from LPC nodes
- Revise LPC bindgins as suggested by Rob

v6:
- Fix another typo in YAML file
- Move sysfs description from bindings to ABI document

v5:
- Fix typo in YAML file to solve the compatible string not found error

v4:
- Convert aspeed-lpc bindings to YAML schema to resolve dependecy issues

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
