Subject: [PATCH v5 0/4] arm: aspeed: Add UART routing support
Date: Thu, 16 Sep 2021 17:25:11 +0800 [thread overview]
Message-ID: <20210916092515.10553-1-chiawei_wang@aspeedtech.com> (raw)
Add UART routing driver and the device tree nodes.
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
