It is available under /sys/devices/soc0/ for user space, and can be checked, where needed, in Kernel using soc_device_match(). It is also required for introducing support for new revisions of K3 AM65x/J721E SoCs. Example J721E: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments K3 J721E SoC J721E SR1.0 Example AM65x: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments AM654 Base Board AM65X SR1.0 Grygorii Strashko (5): dt-bindings: soc: ti: add binding for k3 platforms chipid module soc: ti: add k3 platforms chipid module driver arm64: arch_k3: enable chipid driver arm64: dts: ti: k3-am65-wakeup: add k3 platforms chipid module node arm64: dts: ti: k3-j721e-mcu-wakeup: add k3 platforms chipid module node .../bindings/soc/ti/k3-socinfo.yaml | 40 ++++++ arch/arm64/Kconfig.platforms | 1 + arch/arm64/boot/dts/ti/k3-am65-wakeup.dtsi | 5 + .../boot/dts/ti/k3-j721e-mcu-wakeup.dtsi | 5 + drivers/soc/ti/Kconfig | 10 ++ drivers/soc/ti/Makefile | 1 + drivers/soc/ti/k3-socinfo.c | 135 ++++++++++++++++++ 7 files changed, 197 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/ti/k3-socinfo.yaml create mode 100644 drivers/soc/ti/k3-socinfo.c
