Hi Borislav:
Realtek card reader supports not only SDMMC card, but also Memory stick.
This part is the common code, so it is located in drivers/misc. There is
also SDMMC-relevant code under CONFIG_MMC. And in the future,
Memstick-relevant code will be added under CONFIG_MEMSTICK.

Realtek card reader core driver is the bus driver for Realtek
driver-based card reader, which supplies adapter layer to
be used by lower-level pci/usb card reader and upper-level
sdmmc/memstick host driver.

+Realtek Driver-based Card Reader
+================================
+
+Supported chips:
+RTS5209
+RTS5229
+
+Contact Email:
+pc_sw_linux@xxxxxxxxxxxxxx
+
+
+Description
+-----------
+
+Realtek driver-based card reader supports access to many types of memory cards,
+such as Memory Stick, Memory Stick Pro, Secure Digital and MultiMediaCard.
+
+
+udev rules
+----------
+
+In order to modprobe Realtek SD/MMC interface driver automatically, the following rule
+should be added to the udev rules file:
+
+SUBSYSTEM=="rtsx_cr", ENV{RTSX_CARD_TYPE}=="SD", RUN+="/sbin/modprobe -bv rtsx_sdmmc"
+
+Typically, we may edit /lib/udev/rules.d/80-drivers.rules and copy the rule into it in Ubuntu.

Ok, maybe I'm a newbie here but this is a card reader driver and AFAICT
it should be placed under CONFIG_MMC. Why is it under drivers/misc?
