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.

On some ChromeOS board designs we've got a connection to the EC
|
|
(embedded controller) but no direct connection to some devices on the
|
|
other side of the EC (like a battery and PMIC). To get access to
|
|
those devices we need to tunnel our i2c commands through the EC.
|
|
|
|
The node for this device should be under a cros-ec node like
|
|
google,cros-ec-spi or google,cros-ec-i2c.
