26       property must be set at SoC level DTS files.
28   overrun-character:
31       Configurable, defaults to 0xff (line high), the most common value used

41   wake-gpios:
42     type: phandle-array
44       Optional bi-directional line that allows SPI master to indicate to SPI
45       slave (by setting the line high) that a transfer is to occur, so that
47       transfer when it is actually needed, and stay in any desired low-power
50       - initially, SPI slave configures its WAKE line pin as an input and SPI
52       - when a transfer is to be performed, SPI master configures its WAKE
53         line pin as an input with pull-up; this changes the line state to
54         high but allows SPI slave to override that state
55       - when SPI slave detects the high state of the WAKE line, it prepares
58       - the generated high-to-low transition on the WAKE line is a signal
60       - SPI slave releases the line by configuring its pin back to be an input
