Subject: [PATCH v2 0/3] hwmon: scmi: Scale values to target desired HWMON units
Date: Tue, 7 May 2019 12:35:01 -0700 [thread overview]
Message-ID: <20190507193504.28248-1-f.fainelli@gmail.com> (raw)
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 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 (3):
kernel: Provide a __pow10() function
firmware: arm_scmi: Fetch and store sensor scale
hwmon: scmi: Scale values to target desired HWMON units
