Hi Sascha,

My board is  Phytec phyFLEX-i.MX6 Quad Carrier-Board.
I look to commit 7a037a952da8083e2eddcb2b2e180f0629e83758 Author:
Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>
Date:   Fri Feb 14 11:55:02 2014 +0100

    input: gpio-keys: Add devicetree probe support

    Signed-off-by: Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>

that seem ok.
I look also in boot-up info that nothing indicate that gpio-keys
driver is loaded

I loog to .config that seem be ok
(from my .config)
#
# Drivers
#
CONFIG_OFTREE=y
CONFIG_OFTREE_MEM_GENERIC=y
CONFIG_DTC=y
CONFIG_OFDEVICE=y
CONFIG_OF_NET=y
CONFIG_OF_GPIO=y
CONFIG_OF_BAREBOX_DRIVERS=y

rereading to changes in arch/arm/boards/archosg9 and commit 28ce80f5
it seems that some parts missing in phtec ini sequence but I'm not
sure about it.

Thaks you

Zdenek
