Although rtsx_usb doesn't support card removal detection, card insertion
will resume rtsx_usb by USB remote wakeup signaling.
When rtsx_usb gets resumed, also resumes its child devices,
rtsx_usb_sdmmc and rtsx_usb_ms, to notify them there's a card in its
slot.

This driver provides support for Alcor Micro AU6601 and AU6621
card readers.
This is single LUN HW and it is expected to work with following standards:
- Support SDR104 / SDR50
- MultiMedia Card (MMC)
- Memory Stick (MS)
- Memory Stick PRO (MS_Pro)
Since it is a PCIe controller, it should work on any architecture
supporting PCIe. For now, it was developed and tested only on x86_64.
This driver is a result of RE work and was created without any
documentation or real knowledge of HW internals.

A change to the generic scatterlist code caused a conflict with
the rtsx card reader driver:
In file included from drivers/misc/cardreader/rtsx_pcr.c:32:
include/linux/rtsx_pci.h:40: error: "SG_END" redefined [-Werror]
This changes one instance of the driver to prefix SG_END and
related constants.

Add support for new chip rts5260.
In order to support rts5260, the definitions of
some internal registers and workflow have to be
modified and are different from its predecessors
and OCP function is added for RTS5260. So we need
this patch to ensure RTS5260 can work.

Because Realtek card reader drivers are pcie and usb drivers,
and they bridge mmc subsystem and memstick subsystem, they are
not mfd drivers. Greg and Lee Jones had a discussion about
where to put the drivers, the result is that misc is a good
place for them, so I move all files to misc. If I don't move
them to a right place, I can't add any patch for this driver.
