The ASRock Rack ALTRAD8 BMC is an Aspeed AST2500-based BMC for the ALTRAD8UD-1L2T and ALTRAD8UD2-1L2Q boards with an Ampere Altra processor. The BMC runs OpenBMC. These patches add a device tree and binding for the BMC. **Changes between v2 and v3** - Removed system fault and enclosure identify LEDs; added heartbeat. - Removed the code partition from the BIOS/UEFI flash. - Renoved bus-frequency from i2c nodes. - Renamed hardware-monitor to temperature-sensor. - Fixed indentation of nct7802 subnodes. - Swapped eth0_macaddress and eth1_macaddress. - Removed pca9557 subnodes. - Reworked GPIO names to be more consistent. - Moved documentation of aspeed-pwm-tacho from txt to yaml file. **Testing** Ran `make ARCH=arm CHECK_DTBS=y aspeed/aspeed-bmc-asrock-altrad8.dtb` and verified the messages about the aspeed,pwm-tacho device are no longer present. The remaining messages are: arch/arm/boot/dts/aspeed/aspeed-bmc-asrock-altrad8.dtb: /ahb/apb/lpc@1e789000/lhc@a0: failed to match any schema with compatible: ['aspeed,ast2500-lhc'] arch/arm/boot/dts/aspeed/aspeed-bmc-asrock-altrad8.dtb: /ahb/apb/lpc@1e789000/ibt@140: failed to match any schema with compatible: ['aspeed,ast2500-ibt-bmc'] Rebecca Cran (3): dt-bindings: arm: aspeed: add ASRock Rack ALTRAD8 board ARM: dts: aspeed: add device tree for ASRock Rack ALTRAD8 BMC dt-bindings: hwmon: (aspeed,g5-pwm-tacho) Move info from txt to yaml Documentation/devicetree/bindings/arm/aspeed/aspeed.yaml | 1 + Documentation/devicetree/bindings/hwmon/aspeed,pwm-tacho.yaml | 91 +++ Documentation/devicetree/bindings/hwmon/aspeed-pwm-tacho.txt | 73 --- arch/arm/boot/dts/aspeed/Makefile | 1 + arch/arm/boot/dts/aspeed/aspeed-bmc-asrock-altrad8.dts | 612 ++++++++++++++++++++ 5 files changed, 705 insertions(+), 73 deletions(-) create mode 100644 Documentation/devicetree/bindings/hwmon/aspeed,pwm-tacho.yaml delete mode 100644 Documentation/devicetree/bindings/hwmon/aspeed-pwm-tacho.txt create mode 100644 arch/arm/boot/dts/aspeed/aspeed-bmc-asrock-altrad8.dts -- 2.47.3
