Also tested with 2.6.35-23-omap
Test environment:
Linux ubuntu 2.6.35-23-omap #37-Ubuntu Sat Nov 6 02:01:12 UTC 2010
armv7l GNU/Linux
ubu...@ubuntu:~$ cat /proc/version
Linux version 2.6.35-23-omap (bui...@gourd) (gcc version 4.4.5
(Ubuntu/Linaro 4.4.4-14ubuntu5) ) #37-Ubuntu Sat Nov 6 02:01:12 UTC
2010
Test case 1 : Check GPIO's configuration
ubu...@ubuntu:~$ cat /sys/kernel/debug/gpio | grep GPIO_EHCI_NOC
gpio-193 (GPIO_EHCI_NOC ) in lo
ubu...@ubuntu:~$ cat /sys/kernel/debug/gpio | grep GPIO_USBH_CPEN
gpio-210 (GPIO_USBH_CPEN ) out hi
- Result: PASS, GPIO_EHCI_NOC is configured as input and
GPIO_USBH_CPEN is configured as output.
Note : Seems ehci-omap driver needs some hooks for external VBUS power
switch and overcurrent detect, these GPIOs are missing from the board
initialitzation, if this is not solved the inputs/outputs from these
two sources are ignored.
