currently, i want to enable OTG as device function in i.MX25 platform, kernel is linux-2.6.31 in your L2.6.31_09.12.01_SDK_source,
but in the menuconfig, i didn't find the option of it, it seems that it is forbidden, because configuration options is "*** OTG and related infrastructure ***"
under "USB support".
second, if we suppose we can enable OTG, i glanced at the Kconfig and Make under "linux-2.6.31/drivers/usb/otg",
i'm not sure whether we need configure "CONFIG_UTMI_MXC_OTG", because there is fsl_otg_arc.c which is needed by "CONFIG_UTMI_MXC_OTG".
if i can't enable OTG in linux kernel, Can you supply me another way to embedded OTG function in linux as soon as possible?
Thanks from heart!
