MFR_CALIBRATION is register 0xd4, so I don't think that "MFR_CALIBRATION which will be set into register 0xd4" is a really useful description. Also, the calibration register value is, per datasheet, supposed to be calculated from current_lsb and Rshunt. Since current_lsb is calculated from the maximum expected current, the properties should actually be the maximum expected current and Rshunt. > +Example: > + > + ina233@45 { > + compatible = "ti,ina233"; > + reg = <0x45>; > + resistor-calibration = /bits/ 16 <0x0a00>; > + current-lsb= /bits/ 16 <0x0001>; > + }; > diff --git a/MAINTAINERS b/MAINTAINERS > index bf0f54c24f81..48b9a73d259f 100644 > --- a/MAINTAINERS > +++ b/MAINTAINERS > @@ -10243,6 +10243,12 @@ F: Documentation/devicetree/bindings/hwmon/ti,ina2xx.yaml > F: Documentation/hwmon/ina209.rst > F: drivers/hwmon/ina209.c > > +INA233 HARDWARE MONITOR DRIVER > +M: Delphine CC Chiu <Delphine_CC_Chiu@wiwynn.com> > +S: Odd Fixes > +F: Documentation/devicetree/bindings/hwmon/ina233.txt > +F: drivers/hwmon/ina233.c > + > INA2XX HARDWARE MONITOR DRIVER > M: Guenter Roeck <linux@roeck-us.net> > L: linux-hwmon@vger.kernel.org ^ permalink raw reply [flat|nested] 6+ messages in thread

The datasheet says that R must also be calculated. The datasheet specifically says "Moving the decimal point to maximize the value of m is critical to minimize rounding errors" and "Care must be taken to adjust the exponent coefficient, R, such that the value of m remains within the range of –32768 to 32767". If you think that is not necessary, please explain. Actually, the values for m will never exceed the range but be _much_ less based on above equations, which must result in significant loss of precision. "40 / current_lsb" means the m value for power will never be above 40 and quite likely 0.
