Rob,
I went with the 1-based 'reg' property here. I inferred that that
would be your preference based on the previous thread [1]. Let me
know if that's not the case.

Changes from RFC:
- Removed max-brightness property.
- Added #address-cells and #size-cells properties to the example.

+Binding for ISSI IS31FL32xx LED Drivers
+
+The IS31FL32xx family of LED drivers are I2C devices with multiple
+constant-current channels, each with independent 256-level PWM control.
+Each LED is represented as a sub-node of the device.
+
+Required properties:
+- compatible: one of
+ issi,is31fl3236
+ issi,is31fl3235
+ issi,is31fl3218
+ issi,is31fl3216
+- reg: I2C slave address
+- address-cells : must be 1
+- size-cells : must be 0
+
+LED sub-node properties:
+- reg : LED channel number (1..N)
+- label : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+- linux,default-trigger : (optional)
+ see Documentation/devicetree/bindings/leds/common.txt
+
+
+Example:
+
+leds: is31fl3236@3c {
+ compatible = "issi,is31fl3236";
+ reg = <0x3c>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ led@1 {
+ reg = <1>;
+ label = "EB:blue:usr0";
+ };
+ led@2 {
+ reg = <2>;
+ label = "EB:blue:usr1";
+ };
+ ...
+ led@36 {
+ reg = <36>;
+ label = "EB:blue:usr35";
+ };
+};
