LIS2DS12 is an accelerometer by STMicroelectronics. It is identifiable by
its WhoAmI value 0x43.
Its register interface is not compatible with existing parts. For example:
- The full-scale values are present in register 0x20, in bits 2 and 3
(mask 0x0c). Most other supported sensors have the register address set
to 0x21, 0x23, 0x24, or 0x25. There is one sensor setting though
(bearing WhoAmI 0x3b) which has it's address set to 0x20, but the mask is
set to 0x20, not 0x0c.
- The full-scale values 2G, 4G, 8G, and 16G correspond to the register
values 0x00, 0x02, 0x03, 0x01 respectively. None of the sensor settings
have the value 0x01 associated with 16G.
Add the compatible string without any fallback.

Fix typos in Documentation/devicetree/bindings. The changes are in

The description oddly contains a copy of the initial paragraph.

The ST IIS328DQ is an accelerometer sensor, which is compatible with
the already supported ST H3LIS331DL. So add the new compatible
with a fallback to the ST sensor binding.

The ST LSM303C [1] is a accelerometer and magnetometer combo sensor
compatible with the existing ST sensor bindings. Accelerometer and
magnetometer are exposed through separate I2C/SPI devices, so document
separate compatibles with -accel and -magn suffix.

This chip is not an ST part, but it appears to be register-compatible
with the LIS2DH, so it can use the same binding.

The original bindings was listing the length of the interrupts as either
1 or 2, depending on the setup. This is also what is enforced by the top
level schema.
However, that is further constrained with an if clause that require
exactly two interrupts, even though it might not make sense on those
devices or in some setups.
Let's remove the clause entirely.

This adjusts the ST Sensor bindings with the more fine-grained
syntax checks that were proposed late in the last kernel cycle
and colliding with parallel work.

This binding document covers a very large number of different sensors.
As such the existing documentation is less specific than it could
be (such as which devices have 2 interrupt pin options).
That can be improved later.
Denis, are you happy to be listed as maintainer for this one?
If not feel free to suggestion someone else.
