The example DTS should be indented with two or four (preferred) spaces, as mentioned in Writing Schema document. While re-indenting, change the node names to somehow generic names, as expected by Devicetree specification.

2023-03-08dt-bindings: Fix SPI and I2C bus node names in examplesRob Herring1-1/+1
SPI and I2C bus node names are expected to be "spi" or "i2c", respectively, with nothing else, a unit-address, or a '-N' index. A pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these cases. Mostly scripted with the following commands: git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/' git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/' With this, a few errors in examples were exposed and fixed.
