I found the: "ti,charge-period (sound/ti,tas5086.txt)" binding which represents nearly the same but it is not common. One opportunity would be to introduce a common "charge-period-us" binding and change the ti binding the common binding later.
Are you sure what you have is a charge period and not some stabalization time or something?
According to the data sheet: 8<----- As described in the Digital Core Clock section of the Theory of Operation, insert enough delay time to charge the VMID decoupling capacitor before setting the active bit [Register R9, Bit D0]. 8<----- I think yes, it is a charge period.
Also the formula for the delay time (t = C × 25,000/3.5) depends only on the capacity size.
