From 0b673b6486998061b0489b09447ebe8452da0146 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 8 May 2019 11:46:34 -0700 Subject: firmware: arm_scmi: fetch and store sensor scale In preparation for dealing with scales within the SCMI HWMON driver, fetch and store the sensor unit scale into the scmi_sensor_info structure. In order to simplify computations for upper layer, take care of sign extending the scale to a full 8-bit signed value.
