Also, the preferred names for the nodes would now be led-0 and led-1 (the kernel will assign them more recognizable names in /sys/class/leds based on the color and function attributes). >+ }; >+ >+ 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*/ "", "", "", ""; >+ >+ >+ /* Assert output-bmc-ready to allow the BIOS to continue booting */ >+ bmc-ready { >+ gpio-hog; >+ /* output-bmc-ready */ >+ gpios = <ASPEED_GPIO(J, 0) GPIO_ACTIVE_LOW>; >+ output-high; >+ }; I did this on the e3c246d4i and I'm not sure it was entirely the right choice -- it does solve the problem of avoiding the host's boot sequence sitting there waiting for a timeout to expire before proceeding, but it does so by essentially lying and asserting readiness at all times (when the host is probably expecting that to mean that the BMC is actually prepared to respond to IPMI commands on the KCS interface and such). In practice the only time I think it might cause any noticeable problems is if the host happens to reboot at just the wrong time relative to a BMC reboot, but ideally we'd have some more honest userspace logic to assert it at an appropriate time when it actually means something (though exactly what might be up for some discussion). Under the circumstances this may be the pragmatic approach for now, but if OpenBMC does ever arrive at something to solve that particular problem this would need to be backed out to make room for it. >+}; >+ >+&fmc { >+ status = "okay"; >+ flash@0 { >+ status = "okay"; >+ label = "bmc"; >+ m25p,fast-read; >+ spi-max-frequency = <10000000>; Over-indented block body again here. >+#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>; >+}; >+ >+&mac1 { >+ status = "okay"; >+ pinctrl-names = "default"; >+ pinctrl-0 = <&pinctrl_rmii2_default &pinctrl_mdio2_default>; >+ use-ncsi; >+}; mac0 & mac1 could make use of the recently-added support for retrieving MAC addresses from a location specified by an nvmem-cells property; see https://lore.kernel.org/openbmc/20231120121901.19817-6-zev@bewilderbeest.net/T/#u for an example (already mentioned off-list, just including here for the sake of completeness). >+ >+&i2c0 { >+ status = "okay"; >+}; >+ >+&i2c1 { >+ status = "okay"; >+ >+ w83773g@4c { >+ compatible = "nuvoton,w83773g"; >+ reg = <0x4c>; >+ }; >+}; >+ >+&i2c2 { >+ status = "okay"; >+}; >+ >+&i2c3 { >+ status = "okay"; >+}; >+ >+&i2c4 { >+ status = "okay"; >+ >+ i2c-switch@70 { I'm guessing this mux is for the PCIe slots? (A brief comment indicating that might be nice if so, and maybe which channels are mapped to which specific slots if you happen to have worked that out.) It'd probably also be good to add some aliases for the sub-busses of the mux so they get assigned consistent, predictable numbers. >+ compatible = "nxp,pca9545"; >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <0x70>; >+ >+ interrupt-parent = <&i2c_ic>; >+ interrupts = <4>; >+ interrupt-controller; >+ #interrupt-cells = <2>; >+ >+ i2c@0 { >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <0>; >+ }; >+ >+ i2c@1 { >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <1>; >+ }; >+ >+ i2c@2 { >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <2>; >+ }; >+ >+ i2c@3 { >+ #address-cells = <1>; >+ #size-cells = <0>; >+ reg = <3>; >+ }; >+ }; >+}; >+ >+&i2c5 { >+ status = "okay"; >+}; >+ >+&i2c7 { >+ status = "okay"; >+ >+ eeprom@57 { >+ compatible = "st,24c128", "atmel,24c128"; >+ reg = <0x57>; >+ pagesize = <16>; >+ }; I assume this is the motherboard's FRU eeprom; if so and this is anything like the other ASRR boards I've dealt with, the BMC MAC addresses should be at offsets 0x3f80 (dedicated) and 0x3f88 (NCSI) within it. >+}; >+ >+&gfx { >+ status = "okay"; >+}; >+ >+&pinctrl { >+ aspeed,external-nodes = <&gfx &lhc>; >+}; >+ >+&vhub { >+ status = "okay"; >+}; >+ >+&ehci1 { >+ status = "okay"; >+}; >+&uhci { >+ status = "okay"; >+}; >+ >+&kcs3 { >+ aspeed,lpc-io-reg = <0xca2>; >+ status = "okay"; >+}; >+ >+&lpc_ctrl { >+ status = "okay"; >+}; >+ >+&lpc_snoop { >+ status = "okay"; >+ snoop-ports = <0x80>; >+}; >+ >+&p2a { >+ status = "okay"; >+ memory-region = <&pci_memory>; >+}; >+ >+&video { >+ status = "okay"; >+ memory-region = <&video_engine_memory>; >+}; >+ >+&pwm_tacho { >+ status = "okay"; >+ pinctrl-names = "default"; >+ pinctrl-0 = <&pinctrl_pwm0_default >+ &pinctrl_pwm1_default >+ &pinctrl_pwm2_default >+ &pinctrl_pwm3_default >+ &pinctrl_pwm4_default >+ &pinctrl_pwm5_default>; >+ fan@0 { >+ reg = <0x00>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x00 0x01>; >+ }; >+ fan@1 { >+ reg = <0x01>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x02 0x03>; >+ }; >+ fan@2 { >+ reg = <0x02>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x04 0x05>; >+ }; >+ fan@3 { >+ reg = <0x03>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x06 0x07>; >+ }; >+ fan@4 { >+ reg = <0x04>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x08 0x09>; >+ }; >+ fan@5 { >+ reg = <0x05>; >+ aspeed,fan-tach-ch = /bits/ 8 <0x0a 0x0b>; >+ }; Minor style nit: it's common (and nice IMO) to include a blank line between sibling nodes. >+}; >+ >+&adc { >+ status = "okay"; >+ pinctrl-names = "default"; >+ pinctrl-0 = <&pinctrl_adc0_default >+ &pinctrl_adc1_default >+ &pinctrl_adc2_default >+ &pinctrl_adc3_default >+ &pinctrl_adc4_default >+ &pinctrl_adc5_default >+ &pinctrl_adc6_default >+ &pinctrl_adc7_default >+ &pinctrl_adc8_default >+ &pinctrl_adc9_default >+ &pinctrl_adc10_default >+ &pinctrl_adc11_default >+ &pinctrl_adc12_default >+ &pinctrl_adc13_default >+ &pinctrl_adc14_default >+ &pinctrl_adc15_default>; >+}; >-- >2.43.0 > > _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 6+ messages in thread
