Subject: [PATCH V7 1/3] mmc: sdhci-pci-o2micro: Change O2 Host PLL and DLL register name

[Shirley Her (SC)]

Change O2 Host PLL and DLL register name

Signed-off-by:Shirley Her <shirley.her@xxxxxxxxxxxxxx>
---
change in v7:
 1. change subject

change in V6:
 1. change subject and commit message to match the patch
 2. change register name O2_PLL_WDT_CONTROL1 TO O2_PLL_DLL_WDT_CONTROL1

change in V5:
 1. split 2 patches into 3 patches
 2. make dll_adjust_count start from 0
 3. fix ret overwritten issue
 4. use break instead of goto

change in V4:
 1. add a bug fix for V3

change in V3:
 1. add more explanation in dll_recovery and execute_tuning function
 2. move dll_adjust_count to O2_host struct
 3. fix some coding style error
 4. renaming O2_PLL_WDT_CONTROL1 TO O2_PLL_DLL_WDT_CONTROL1

change in V2:
 1. use usleep_range instead of udelay
 2. move dll_adjust_count to sdhci-pci-o2micro.c

chagne in V1:
 1. add error recovery function to relock DLL with correct phase
 2. retuning HS200 after DLL locked
