4D cape button readback using python

Hello to support,

Having an issue trying to readback the state of the buttons on the 4D cape. I have confirmed the proper wiring

left P9.15 GPIO1_16
right P9.23 GPIO1_17
up P9.16 GPIO1_19
down P9.30 GPIO3_16
enter P9.21 GPIO0_3

running 3.8.13-bone47

The 7" LCD display works. When trying to access the pins connected to the buttons directly or through python get the message that the device or resource is busy. I see that the pins seem to be part of the LCD overlay being defined as device gpio_keys.13.

When I cat the slots I get the following
0: 54:P—L 4D 7.0 LCD CAPE- 4DCAPE-70T ,00A3,4D SYSTEMS ,BB-BONE-LCD7-01
1: 55:PF—
2: 56:PF—
3: 57:PF—
4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G

Doing a cat of gpio returns
GPIOs 0-31, gpio:
gpio-2 (lcdc_drv:PDN ) out hi
gpio-3 (enter ) in hi
gpio-6 (mmc_cd ) in hi

GPIOs 32-63, gpio:
gpio-48 (left ) in hi
gpio-49 (right ) in hi
gpio-51 (up ) in hi
gpio-52 (eMMC_RSTn ) out lo
gpio-53 (beaglebone:green:usr) out lo
gpio-54 (beaglebone:green:usr) out lo
gpio-55 (beaglebone:green:usr) out hi
gpio-56 (beaglebone:green:usr) out lo
gpio-60 (lcd7:green:usr0 ) out lo

GPIOs 64-95, gpio:

GPIOs 96-127, gpio:
gpio-112 (down ) in hi

I see the pins but just can’t seem to access them

I seem to be doing something wrong, Do I need to create a device tree overlay to access this pins?

Thanks for any help,
