[PATCH 1/2] dt-bindings: iio: magnetometer: add Infineon TLE493D-W2B6

[Viral Patel <viral8854@gmail.com>]

Add a binding for the Infineon TLE493D-W2B6, a 3D Hall effect magnetic
sensor with 12-bit resolution per axis and an integrated temperature
sensor, accessed over I2C. The A0 to A3 variants of the part only differ
in their default I2C address, so a single compatible covers all of them.

The sensor's /INT output shares a pin with SCL and cannot be wired to an
interrupt controller as a separate line, so there is no interrupts
property.

+description: |
+  Infineon TLE493D-W2B6 3D Hall effect magnetic sensor with an I2C interface
+  and an integrated temperature sensor. The A0, A1, A2 and A3 variants only
+  differ in their default I2C address (0x35, 0x22, 0x78 and 0x44).
+
+  The sensor's /INT output shares a pin with SCL, so it cannot be routed to
+  an interrupt controller as a separate line. The binding therefore has no
+  interrupts property.
