+title: Honeywell TruStability HSC and SSC pressure sensor series
+
+description: |
+  support for Honeywell TruStability HSC and SSC digital pressure sensor
+  series.
+
+  These sensors have either an I2C, an SPI or an analog interface. Only the
+  digital versions are supported by this driver.
+
+  There are 118 models with different pressure ranges available in each family.
+  The vendor calls them "HSC series" and "SSC series". All of them have an
+  identical programming model but differ in pressure range, unit and transfer
+  function.
+
+  To support different models one needs to specify the pressure range as well
+  as the transfer function. Pressure range can either be provided via
+  pressure-triplet (directly extracted from the part number) or in case it's
+  a custom chip via numerical range limits converted to pascals.
+
+  The transfer function defines the ranges of raw conversion values delivered
+  by the sensor. pmin-pascal and pmax-pascal corespond to the minimum and
+  maximum pressure that can be measured.
+
+  Please note that in case of an SPI-based sensor, the clock signal should not
+  exceed 800kHz and the MOSI signal is not required.
+
+  Specifications about the devices can be found at:
