[PATCH 1/2] ARM: dts: ux500: samsung-golden: Add proximity sensor

[PATCH 1/2] ARM: dts: ux500: samsung-golden: Add proximity sensor

[Stephan Gerhold]

samsung-golden has the same sharp,gp2ap002s00f proximity sensor
that is also used in samsung-skomer.

A driver was added for it in
commit 97d642e23037 ("iio: light: Add a driver for Sharp GP2AP002x00F").

Now that it was merged we can add an entry for it in the device tree
for samsung-golden.

Ooops I saw now that I already had this in my "Skomer and misc"
enablement patch. (rebasing my trees today).

I can put this in front of that patch and take it out of mine if you
prefer stepwise enablement.

Yours,
Linus Walleij

Do you mean the "ARM: defconfig: u8500: Enable new drivers for ux500"
patch? It doesn't matter which commit/patch adds it, as long as it ends
up in the u8500_defconfig :)

Thanks,
Stephan
