Change O2 Host PLL and DLL register name
Signed-off-by: Shirley Her <[email protected]>
---
change in V8:
1. fix patch format error
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

It seems like you managed to post the version 8, two times. Is there
any difference? Which one should we review?

Sorry about the confusion and they are the same, please review the 2nd one. One of the email address is wrong when I send the 1st one.
Thanks for your help,
