Subject: [PATCH v3 02/10] iio: accel: bmc150: Clarify combo modules in Kconfig
Date: Fri, 11 Jun 2021 10:08:55 +0200	[thread overview]
Message-ID: <20210611080903.14384-3-stephan@gerhold.net> (raw)
In-Reply-To: <20210611080903.14384-1-stephan@gerhold.net>

The Kconfig option currently says that all Bosch accelerometers
supported by the bmc150-accel driver are combo chips with both
accelerometer and magnetometer. This is wrong: actually only BMC150
is such a combo. The BMA* variants only contain an accelerometer
and the BMI055 actually is a accelerometer + gyroscope combo.

Clarify this in the help text and also make the list of supported
variants complete and sorted for consistency.

 	  Say yes here to build support for the following Bosch accelerometers:
-	  BMC150, BMI055, BMA250E, BMA222E, BMA255, BMA280.
+	  BMA222, BMA222E, BMA250E, BMA255, BMA280, BMC150, BMI055.
+
+	  Note that some of these are combo modules:
+	    - BMC150: accelerometer and magnetometer
+	    - BMI055: accelerometer and gyroscope
 
-	  This is a combo module with both accelerometer and magnetometer.
 	  This driver is only implementing accelerometer part, which has
 	  its own address and register map.
