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 fd7c58ee3026 ("firmware: arm_scmi: Fix locking in notifications") Any feedback welcome, Thanks, Cristian --- v1 --> v2 - rebased on for-next/scmi v5.10 - DT bindings - removed any reference to negative voltages - SCMI Regulator - removed duplicate regulator naming - removed redundant .get/set_voltage ops: only _sel variants implemented - removed condexpr on fail path to increase readability - VD Protocol - fix voltage levels query loop to reload full cmd description between iterations as reported by Etienne Carriere - ensure transport rx buffer is properly sized calli scmi_reset_rx_to_maxsz between transfers [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 | 42 ++ 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 | 382 +++++++++++++++ drivers/regulator/Kconfig | 9 + drivers/regulator/Makefile | 1 + drivers/regulator/scmi-regulator.c | 453 ++++++++++++++++++ include/linux/scmi_protocol.h | 64 +++ 9 files changed, 956 insertions(+), 1 deletion(-) create mode 100644 drivers/firmware/arm_scmi/voltage.c create mode 100644 drivers/regulator/scmi-regulator.c -- 2.17.1
