[PATCH v3 04/15] phy: phy-rockchip-samsung-hdptx: Rename some register names related to DP
Posted by Damon Ding 12 months ago 
The modifications of DP register names are as follows:
- Add the '_MASK' suffix to some registers to ensure consistency.
- Complete the names of some register to their full names.
- Swap the definitions of LCPLL_REF and ROPLL_REF.

Three unrelated changes, ideally means three commits (I won't insist on
that though). Also please mention that LCPLL_REF and ROPLL_REF were not
used by the existing driver, so it's not a bug and there is no need to
backport it.

Indeed, it would be better to split this patch into three different 
commits. However, I still want to keep the fixes for LCPLL_REF and 
ROPLL_REF because, according to the datasheet, they are indeed 
incorrect. And I will describe the suggestions you mentioned in the 
commit message.
