Please note the serial number is currently available only for the S500 SoC variant. This has been tested on the S500 SoC based RoseapplePi SBC. Thanks, Cristi Changes in v2: - Exposed the memory range for reading the SoC serial number under /reserved-memory DT node, according to Rob's review; as a consequence added a new binding document (actions,owl-soc-serial.yaml) and updated owl-socinfo.yaml - Replaced the unportable usage of system_serial_{low,high} globals with a public API to provide external access to SoC serial number parts (e.g. Owl Ethernet MAC driver will use this to generate a stable MAC address) - Rebased patch series on v5.12-rc5 Cristian Ciocaltea (6): dt-bindings: reserved-memory: Add Owl SoC serial number binding dt-bindings: soc: actions: Add Actions Semi Owl socinfo binding soc: actions: Add Actions Semi Owl socinfo driver arm: dts: owl-s500: Add reserved-memory range for Owl SoC serial number arm: dts: owl-s500: Add socinfo support MAINTAINERS: Add entries for Owl reserved-memory and socinfo bindings .../actions,owl-soc-serial.yaml | 53 ++++++ .../bindings/soc/actions/owl-socinfo.yaml | 57 +++++++ MAINTAINERS | 2 + arch/arm/boot/dts/owl-s500.dtsi | 13 +- drivers/soc/actions/Kconfig | 8 + drivers/soc/actions/Makefile | 1 + drivers/soc/actions/owl-socinfo.c | 152 ++++++++++++++++++ include/linux/soc/actions/owl-serial-number.h | 20 +++ 8 files changed, 305 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/reserved-memory/actions,owl-soc-serial.yaml create mode 100644 Documentation/devicetree/bindings/soc/actions/owl-socinfo.yaml create mode 100644 drivers/soc/actions/owl-socinfo.c create mode 100644 include/linux/soc/actions/owl-serial-number.h -- 2.31.1
