This parameter is dynamically generated at runtime on the device and insuitable to pass via the devicetree. The capability-id is stored by firmware in the shmem region. This has been tested on ARM64 virtual Qualcomm platform. --- v6 -> use unsigned long for cap-id v5 -> changed compatible, removed polling support patch, make use of smc-id binding for function-id v4 -> port the changes into smc.c v3 -> fix the compilation error reported by the test bot, add support for polling based instances v2 -> use allOf construct in dtb schema, remove wrappers from mutexes, use architecture independent channel layout v1 -> original patches Nikunj Kela (2): dt-bindings: arm: Add new compatible for smc/hvc transport for SCMI firmware: arm_scmi: Add qcom smc/hvc transport support .../bindings/firmware/arm,scmi.yaml | 4 +++ drivers/firmware/arm_scmi/driver.c | 1 + drivers/firmware/arm_scmi/smc.c | 27 +++++++++++++++++-- 3 files changed, 30 insertions(+), 2 deletions(-) -- 2.17.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
