[PATCH v2 02/17] dt-bindings: olpc,xo1.75-ec: Add OLPC XO-1.75 EC bindings

2018-11-16 Thread Lubomir Rintel
The OLPC XO-1.75 Embedded Controller is a SPI master that uses extra signals for handshaking. It needs to know when is the slave (Linux) side's TX FIFO ready for transfer (the ready-gpio signal on the SPI controller node) and when does it wish to respond with a command (the cmd-gpio property).
