+Hwmon driver for Juniper fan trays on I2CS Slave FPGA

This is a h/w description, not a driver.

quoted

+
+Required properties:
+
+- compatible: "i2cs-fan-hwmon"

I doubt any fan control h/w has "hwmon" in the name.

quoted

+
+Optional properties:
+
+- num-fans: fans per tray (default 14)
+
+- tach-factor: TACH count scaling factor (default 120)

vendor prefixes needed.

quoted

+
+Example:
+
+fan-hwmon {
+	compatible = "jnx,i2cs-fan-hwmon";
+	num-fans = <6>;
+	tach-factor = <33>;
+};

OK on all three.
