>From what I can tell, the omap_hsmmc device driver depends on the GPIO drivers

first, which in turn depend on the I2C layer to be initialized first, in order
for the card
detection logic to work. If either I2C or GPIO gets initialized after MMC, the
driver has
no way of detecting the presence of the card.
So far everything looks good:
* omap_i2c_init_driver is a subsys_initcall
* beagle_twl_gpio_setup gets called from gpio_twl4030_init
* gpio_twl4030_init is a subsys_initcall as well
* The mmc platform device is added through a complicated setup method in
gpio_twl4030_init
* omap_hsmmc_init is a regular initcall
This may be different if the twl4030 or the i2c_omap driver is not built into
the
kernel but omap_hsmmc is, or if they are all modules and loaded in a different
order.
