The irq-gpios description misleading, apparently saying that driving the
IRQ GPIO resets the device, which is even more puzzling as there is a reset
GPIO as well.
In reality the IRQ pin can be driven during the reset sequence to configure
the client address, as it becomes clear after checking both the datasheet
and the driver code. Improve the text to clarify that.
Also rephrase to remove reference to the driver, which is not appropriate
in the bindings.
