+
+description: |
+ This binding describes the Embedded Controller acting as a SPI bus master
+ on a OLPC XO-1.75 laptop computer.
+
+ The embedded controller requires the SPI controller driver to signal
+ readiness to receive a transfer (that is, when TX FIFO contains the
+ response data) by strobing the ACK pin with the ready signal. See the
+ "ready-gpios" property of the SSP binding as documented in:
+ <Documentation/devicetree/bindings/spi/marvell,mmp2-ssp.yaml>.
