Subject: [PATCH RESEND] dt-bindings: trivial-devices: Document SPI measurement on LWE boards
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.
