Hi Sudeep, Guenter, This patch series adds support for scaling SCMI sensor values read from firmware. Sudeep, let me know if you think we should be treating scale == 0 as a special value to preserve some firmware compatibility (not that this would be desired). Changes in v3: - add a local __pow10 function to scmi-hwmon.c while a plan to provide a generic function is figured out. - add check on power > 18 which would overflow a 64-bit unsigned integer - use div64_u64() to properly divide a 64-bit quantity with an unsigned 64-bit quantity Changes in v2: - added a helper function in kernel.h: __pow10() - made the scale in scmi_sensor_info an s8 type, added defines for checking the sign bit and sign extending with a mask - simplify computations in hwmon driver Florian Fainelli (2): firmware: arm_scmi: Fetch and store sensor scale hwmon: scmi: Scale values to target desired HWMON units drivers/firmware/arm_scmi/sensors.c | 6 ++++ drivers/hwmon/scmi-hwmon.c | 43 ++++++++++++++++++++++++++++- include/linux/scmi_protocol.h | 1 + 3 files changed, 49 insertions(+), 1 deletion(-) -- 2.17.1
