[PATCH v3 02/10] spi: dw: Rename "cs-gpio" to "cs-gpios"

[Sean Anderson]

This property is named differently than other SPI drivers with the same
property, as well as the property as used in Linux.

AFAIK these device trees are not synced with Linux. However, if they are,
they have not been synced since this property was renamed in Linux.
