This patchset introduces ExynosAuto v920 SoC ufs phy driver as
Generic PHY driver framework.
Changes from v3:
- Use lower case for all addresses
- Add empty line between macro and function
Changes from v2:
- simplify function name from samsung_exynosautov920_ufs_phy_wait_cdr_lock
to exynosautov920_ufs_phy_wait_cdr_lock
- return immediately after getting the CDR lock
- add comment for wait CDR lock
Changes from v1:
- use exynosautov920 instead of exynosauto to specify
- remove obvious comment
- change soc name as ExynosAutov920 to keep consistent
- use macros instead of magic numbers
- specify function name
- add error handling for CDR lock failure

Add UFS Phy for ExynosAutov920
Like ExynosAutov9, this also uses fixed-rate clock nodes until clock driver
has been supported. The clock nodes are initialized on bootloader stage
thus we don't need to control them so far.
