Looks like I was mislead with the errors and though the twl4030 gpio probe was bailing out with errors, which its not. It does seem to go ahead, does a mmc late init which registers the mmc omap_device and hence does a platform_device_add, but the device never seem to get probed. mmc driver is built in and registered. > > # insmod gpio-twl4030.ko > [ 16.217864] twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules > [ 16.242004] gpiochip_add: registered GPIOs 192 to 211 on device: twl4030 > > >> 4.
