(adding devicetree mailing list) I placed the IR receiver under the root node after looking at what other boards do, for example: imx6dl-hummingboard.dts imx6qdl-cubox-i.dtsi dove-cubox.dts On the other hand, if gpio-keys and leds are under the soc node probably it makes sense to follow the same rule also for the IR receiver.

I'll add the patch to my queue. Heiko

This adds a device tree node for the infrared receiver connected to a GPIO pin on the Radxa Rock. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> --- arch/arm/boot/dts/rk3188-radxarock.dts | 13 +++++++++++++ 1 file changed, 13 insertions(+)
