Hi Midhun, I think mmc driver is layered modules, only top block driver registers driver under "mmc_bus_type" bus, see drivers/mmc/mmc_sysfs.c and mmc_block.c. I think they are creating a tree of devices of same characteristics under that bus. I think your driver is linux/drivers/mmc/imxmmc.c where it registers a driver for device of type "platform_bus_type". This module will come under above mentioned block driver. Corresponding platform device is registered in linux/arch/arm/mach-imx/generic.c see platform_device imx_mmc_device.

Hi All, I have an MMC driver for my kit (i.MX21 based cogent board CSB535FS), which is supplied by Cogent (Kernel version 2.6.16). The original driver (linux/drivers/mmc/mmc_block.c) uses mmc_register_driver() method to register the driver but the one supplied by Cogent uses platform_driver_register() method. What is the difference between the two?
