Summary
=======
This series adds to support New card reader rts5264
patch#1
Going to have new files to define rts5264 funtions,
and rts5264 register definition
patch#2
Add rts5264 to rtsx_pcr driver
patch#3
This new reader rts5264 can support sd express card
so need add the id to ths sd_init flow of rtsx_sdmmc
Patch structure
===============
v6->v7:
move modifications of rtsx_pci.h to patch#1
v5->v6:
add more description for individual patches
v4->v5:
add summary for this series
v3->v4:
split new definition part up from same patch
v2->v3:
split misc part and mmc part
v1->v2:
remove ic version check for rts5264
Ricky Wu(3):
misc: rtsx: add to support new card reader rts5264 new
definition and function
misc: rtsx: add to support new card reader rts5264
mmc: rtsx: add rts5264 to support sd express card

Kind regards
