-OLPC XO-1.75 Embedded Controller
-
-Required properties:
-- compatible: Should be "olpc,xo1.75-ec".
-- cmd-gpios: gpio specifier of the CMD pin
-
-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/spi-pxa2xx.txt>.
-
-Example:
- &ssp3 {
- spi-slave;
- ready-gpios = <&gpio 125 GPIO_ACTIVE_HIGH>;
-
- slave {
- compatible = "olpc,xo1.75-ec";
- spi-cpha;
- cmd-gpios = <&gpio 155 GPIO_ACTIVE_HIGH>;
- };
- };
