RE: [PATCH 1/2] Documentation: Device Tree binding information for gpio-joy driver

The binding should be for a class of hardware, not for a driver. Please
describe the class of hardware the binding represents, and remove
references to the Linux driver.

Will do.

+Required properties:
+	- compatible    = "gpio-joy";

That does not strike me as a very informative compatible string. At the least,
s/joy/joystick/.

You're very right, gpio-joystick is better and as about as specific as it can be I believe.

+	- left-gpio     : gpio connected to the "left" joystick signal
+	- right-gpio    : gpio connected to the "right" joystick signal
+	- up-gpio       : gpio connected to the "up" joystick signal
+	- down-gpio     : gpio connected to the "down" joystick signal
+	- button-gpio   : gpio connected to the "button" joystick signal

Only one button?

Hmm, yes, but it would make more sense to have sub-nodes defining an arbitrary 
number of buttons instead, right?

Thanks for reviewing!
