There *is* some automated tooling to check DTs against the bindings that should flag things like that -- see the bits regarding 'make dtbs_check' in Documentation/devicetree/bindings/writing-schema.rst. However, in its current state it's (a) somewhat fragile and easy to invoke wrong without getting any indication of it (IME, make sure to also pass ARCH=arm on the make command-line), and (b) will probably dump a pretty large quantity of output of which very little pertains to the actual .dts you're adding, which makes it less useful than would be ideal. >+ }; >+ >+ iio-hwmon { >+ compatible = "iio-hwmon"; >+ io-channels = <&adc 0>, <&adc 1>, <&adc 2>, <&adc 3>, <&adc 4>, >+ <&adc 5>, <&adc 6>, <&adc 7>, <&adc 8>, <&adc 9>, >+ <&adc 10>, <&adc 11>, <&adc 12>; >+ }; >+}; >+ >+&gpio { >+ status = "okay"; >+ gpio-line-names = >+ /*A0-A3*/ "status-locatorled-n", "", "button-nmi-n", "", >+ /*A4-A7*/ "", "", "", "", >+ /*B0-B3*/ "input-bios-post-cmplt-n", "", "", "", >+ /*B4-B7*/ "", "", "", "", >+ /*C0-C3*/ "", "", "", "", >+ /*C4-C7*/ "", "", "control-locatorbutton", "", >+ /*D0-D3*/ "button-power", "control-power", "button-reset", "control-reset", >+ /*D4-D7*/ "", "", "", "", >+ /*E0-E3*/ "", "", "", "", >+ /*E4-E7*/ "", "", "", "", >+ /*F0-F3*/ "", "", "", "", >+ /*F4-F7*/ "", "", "", "", >+ /*G0-G3*/ "output-rtc-battery-voltage-read-enable", "input-id0", "input-id1", "input-id2", >+ /*G4-G7*/ "input-alert1-n", "input-alert2-n", "input-alert3-n", "", >+ /*H0-H3*/ "", "", "", "", >+ /*H4-H7*/ "input-mfg", "", "led-heartbeat-n", "input-caseopen", >+ /*I0-I3*/ "", "", "", "", >+ /*I4-I7*/ "", "", "", "", >+ /*J0-J3*/ "output-bmc-ready", "", "", "", >+ /*J4-J7*/ "", "", "", "", >+ /*K0-K3*/ "", "", "", "", >+ /*K4-K7*/ "", "", "", "", >+ /*L0-L3*/ "", "", "", "", >+ /*L4-L7*/ "", "", "", "", >+ /*M0-M3*/ "", "", "", "", >+ /*M4-M7*/ "", "", "", "", >+ /*N0-N3*/ "", "", "", "", >+ /*N4-N7*/ "", "", "", "", >+ /*O0-O3*/ "", "", "", "", >+ /*O4-O7*/ "", "", "", "", >+ /*P0-P3*/ "", "", "", "", >+ /*P4-P7*/ "", "", "", "", >+ /*Q0-Q3*/ "", "", "", "", >+ /*Q4-Q7*/ "", "", "", "", >+ /*R0-R3*/ "", "", "", "", >+ /*R4-R7*/ "", "", "", "", >+ /*S0-S3*/ "input-bmc-pchhot-n", "", "", "", >+ /*S4-S7*/ "", "", "", "", >+ /*T0-T3*/ "", "", "", "", >+ /*T4-T7*/ "", "", "", "", >+ /*U0-U3*/ "", "", "", "", >+ /*U4-U7*/ "", "", "", "", >+ /*V0-V3*/ "", "", "", "", >+ /*V4-V7*/ "", "", "", "", >+ /*W0-W3*/ "", "", "", "", >+ /*W4-W7*/ "", "", "", "", >+ /*X0-X3*/ "", "", "", "", >+ /*X4-X7*/ "", "", "", "", >+ /*Y0-Y3*/ "", "", "", "", >+ /*Y4-Y7*/ "", "", "", "", >+ /*Z0-Z3*/ "", "", "led-fault-n", "output-bmc-throttle-n", >+ /*Z4-Z7*/ "", "", "", "", >+ /*AA0-AA3*/ "input-cpu1-thermtrip-latch-n", "", "input-cpu1-prochot-n", "", >+ /*AA4-AC7*/ "", "", "", "", >+ /*AB0-AB3*/ "", "", "", "", >+ /*AB4-AC7*/ "", "", "", "", >+ /*AC0-AC3*/ "", "", "", "", >+ /*AC4-AC7*/ "", "", "", ""; >+}; >+ >+&fmc { >+ status = "okay"; >+ flash@0 { >+ status = "okay"; >+ label = "bmc"; >+ m25p,fast-read; >+ spi-max-frequency = <10000000>; >+#include "openbmc-flash-layout-64.dtsi" >+ }; >+}; >+ >+&uart5 { >+ status = "okay"; >+}; >+ >+&vuart { >+ status = "okay"; >+}; >+ >+&mac0 { >+ status = "okay"; >+ pinctrl-names = "default"; >+ pinctrl-0 = <&pinctrl_rgmii1_default &pinctrl_mdio1_default>; >+ >+ nvmem-cells = <ð0_macaddress>; >+ nvmem-cell-names = "mac-address"; >+}; >+ >+&mac1 { >+ status = "okay"; >+ pinctrl-names = "default"; >+ pinctrl-0 = <&pinctrl_rmii2_default &pinctrl_mdio2_default>; >+ use-ncsi; >+ >+ nvmem-cells = <ð1_macaddress>; >+ nvmem-cell-names = "mac-address"; >+}; >+ >+&i2c0 { >+ status = "okay"; >+}; >+ >+&i2c1 { >+ status = "okay"; >+ >+ w83773g@4c { >+ compatible = "nuvoton,w83773g"; >+ reg = <0x4c>; >+ }; >+}; >+ >+&i2c2 { >+ status = "okay"; >+}; >+ >+&i2c3 { >+ status = "okay"; >+}; >+ >+&i2c4 { >+ status = "okay"; >+ >+ i2c-mux@70 { >+ compatible = "nxp,pca9545"; >+ reg = <0x70>; >+ #address-cells = <1>; >+ #size-cells = <0>; >+ >+ i2c4mux0ch0@0 { >+ /* SMBus on PCI express 16x slot */ >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <0>; >+ }; >+ >+ i2c4mux0ch1@1 { >+ /* SMBus on PCI express 8x slot */ >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <1>; >+ }; >+ >+ i2c4mux0ch2@2 { >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <2>; >+ }; >+ >+ i2c4mux0ch3@3 { >+ /* SMBus on PCI express 1x slot */ >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <3>; >+ }; >+ }; Comments here are good, thanks -- was leaving out the suggested bus aliases an intentional choice or just an oversight though?

This is a relatively low-cost AST2500-based Amd Ryzen 5000 Series micro-ATX board that we hope can provide a decent platform for OpenBMC development. This initial device-tree provides the necessary configuration for basic BMC functionality such as serial console, KVM support and POST code snooping.
