The transport is mechanically similar to ARM_SCMI_TRANSPORT_SMC. The difference between the two transports is that a parameter is passed in the hypervisor call to identify which doorbell to assert. This parameter is dynamically generated at runtime on the device and insuitable to pass via the devicetree. The function ID and parameter are stored by firmware in the shmem region. This has been tested on ARM64 virtual Qualcomm platform. --- 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 (3): dt-bindings: arm: convert nested if-else construct to allOf dt-bindings: arm: Add qcom specific hvc transport for SCMI firmware: arm_scmi: Add qcom hvc/shmem transport .../bindings/firmware/arm,scmi.yaml | 67 ++--- drivers/firmware/arm_scmi/Kconfig | 13 + drivers/firmware/arm_scmi/Makefile | 2 + drivers/firmware/arm_scmi/common.h | 3 + drivers/firmware/arm_scmi/driver.c | 4 + drivers/firmware/arm_scmi/qcom_hvc.c | 232 ++++++++++++++++++ 6 files changed, 293 insertions(+), 28 deletions(-) create mode 100644 drivers/firmware/arm_scmi/qcom_hvc.c
