We were right about to develop a proprietary SCMI protocol in order to control a locked down PMIC accessible behind a secured firmware. We would have done essentially just that since the use case is to control the various regulators exposed by this PMIC over SCMI.

Hi, this series introduces the support for the new SCMI Voltage Domain Protocol defined by the upcoming SCMIv3.0 specification, whose BETA release is available at [1]. Afterwards, a new generic SCMI Regulator driver is developed on top of the new SCMI VD Protocol. The series is currently based on for-next/scmi [2] on top of: commit 66d90f6ecee7 ("firmware: arm_scmi: Enable building as a single module") Any feedback welcome, Thanks, Cristian [1]:https://developer.arm.com/documentation/den0056/c/ [2]:https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git/log/?h=for-next/scmi Cristian Marussi (4): firmware: arm_scmi: Add Voltage Domain Support firmware: arm_scmi: add SCMI Voltage Domain devname regulator: add SCMI driver dt-bindings: arm: add support for SCMI Regulators .../devicetree/bindings/arm/arm,scmi.txt | 44 ++ drivers/firmware/arm_scmi/Makefile | 2 +- drivers/firmware/arm_scmi/common.h | 1 + drivers/firmware/arm_scmi/driver.c | 3 + drivers/firmware/arm_scmi/voltage.c | 378 ++++++++++++++ drivers/regulator/Kconfig | 9 + drivers/regulator/Makefile | 1 + drivers/regulator/scmi-regulator.c | 488 ++++++++++++++++++ include/linux/scmi_protocol.h | 64 +++ 9 files changed, 989 insertions(+), 1 deletion(-) create mode 100644 drivers/firmware/arm_scmi/voltage.c create mode 100644 drivers/regulator/scmi-regulator.c
