I guess if you do insist on adding comments for this (not necessary IMO),
we could improve on the stylistic elegance by saying "Standard CS timing
properties replace the deprecated vendor variants below" or something
like that. But currently it doesn't look great when there is a verb in
the present tense and another in the past tense. Also, the plural form
should have been used for 'property'.

Additionally, I don't believe that a new line between the groups of
properties is necessary.

Do you plan on deprecating the fsl, CS timing parameters tree-wide, or
are you going to stop at the LS1043A-RDB?
