+* Cr50 Chip on SPI.
+
+TCG PTP FIFO Compliant Interface to Cr50 on SPI bus.
+
+Required properties:
+- compatible: Should be "google,cr50_spi".
+- spi-max-frequency: Maximum SPI frequency.
+
+Optional properties:
+- access-delay-msec: Required delay between subsequent transactions on SPI.
+- sleep-delay-msec: Time after the last SPI activity, after which the chip
+ may go to sleep.
+- wake-start-delay-msec: Time after initiating wake up before the chip is
+ ready to accept commands over SPI.
+
+Example:
+
+&spi0 {
+ status = "okay";
+
+ cr50@0 {
+ compatible = "google,cr50_spi";
+ reg = <0>;
+ spi-max-frequency = <800000>;
+
+ access-delay-msec = <2>;
+ sleep-delay-msec = <1000>;
+ wake-start-delay-msec = <60>;
+ };
+};
