Update the properties for the lm3532 device node for droid4.
With this change the backlight LED string and the keypad
LED strings will be controlled separately.

v5 - No change - https://lore.kernel.org/patchwork/patch/1050409/

v4 - No change - https://lore.kernel.org/patchwork/patch/1050125/
v3 - updated keypad label on v1 comment - https://lore.kernel.org/patchwork/patch/1049023/
v2 - Fixed ramp-up and ramp-down properties, removed hard coded property values,
I did not change the label as it is undecided what it could be - https://lore.kernel.org/patchwork/patch/1048806/

Since I'll be creating integration branch for this series,
and it would be good to have this patch in it too, then
I can do the amendments by myself:

+ lcd_backlight: led@0 {
+ reg = <0>;
+ led-sources = <2>;
+ ti,led-mode = <0>;
+ label = "backlight";

s/backlight/:backlight/

+ linux,default-trigger = "backlight";
+ };
+
+ led@1 {
+ reg = <1>;
+ led-sources = <1>;
+ ti,led-mode = <0>;
+ label = "platform::kbd_backlight";

s/platform::kbd_backlight/:kbd_backlight/

and then send you a pull request.

Would you be OK with that?

};
