[PATCH v2] dt-bindings: trivial-devices: Document SPI measurement on LWE boards
From: Lukasz Majewski
Date: Wed Mar 26 2025 - 13:20:47 EST
The measurement device on Liebherr's (LWE) boards is used to monitor
the overall state of the device. It does have SPI interface to
communicate with Linux host via spidev driver. Document the SPI DT
binding as trivial SPI device.

Changes for v2:
- Use already in-kernel available 'lwn' vendor prefix instead of introducing
a new one
