Add UART routing driver and the device tree nodes. 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 Chia-Wei Wang (4): dt-bindings: mfd: aspeed-lpc: Convert to YAML schema dt-bindings: aspeed: Add UART routing controller soc: aspeed: Add UART routing support ARM: dts: aspeed: Add uart routing to device tree .../testing/sysfs-driver-aspeed-uart-routing | 15 + .../devicetree/bindings/mfd/aspeed-lpc.txt | 157 ----- .../devicetree/bindings/mfd/aspeed-lpc.yaml | 191 ++++++ .../bindings/soc/aspeed/uart-routing.yaml | 70 ++ arch/arm/boot/dts/aspeed-g4.dtsi | 6 + arch/arm/boot/dts/aspeed-g5.dtsi | 6 + arch/arm/boot/dts/aspeed-g6.dtsi | 6 + drivers/soc/aspeed/Kconfig | 10 + drivers/soc/aspeed/Makefile | 9 +- drivers/soc/aspeed/aspeed-uart-routing.c | 603 ++++++++++++++++++ 10 files changed, 912 insertions(+), 161 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-driver-aspeed-uart-routing delete mode 100644 Documentation/devicetree/bindings/mfd/aspeed-lpc.txt create mode 100644 Documentation/devicetree/bindings/mfd/aspeed-lpc.yaml create mode 100644 Documentation/devicetree/bindings/soc/aspeed/uart-routing.yaml create mode 100644 drivers/soc/aspeed/aspeed-uart-routing.c -- 2.17.1
