2018-11-13spi: pxa2xx: dt-bindings: Add ready GPIO signalLubomir Rintel
This this is used to let the SPI master know that our FIFO is filled and we're ready to service a transfer. Only useful in slave mode. A signal like this is used by an embedded controller on a OLPC XO 1.75 machine, that happens to be a SPI master.
