In order to support new chip rts5228, the definitions of some internal registers and workflow have to be modified.

2020-05-22misc: rtsx: Use pcie_capability_clear_and_set_word() for PCI_EXP_LNKCTLBjorn Helgaas
Instead of using the driver-specific rtsx_pci_update_cfg_byte() to update the PCIe Link Control Register, use pcie_capability_clear_and_set_word() like the rest of the kernel does. This makes it easier to maintain ASPM across the PCI core and drivers. Remove the now-unused rtsx_pci_update_cfg_byte() and ASPM_MASK_NEG definitions. No functional change intended.

2017-11-29misc: rtsx: Move Realtek Card Reader Driver to miscRui Feng
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.
