Subject: Re: [PATCH v4 3/6] mfd: ti_am335x_tscadc: Remove unwanted
 reg_se_cache save

Before the patches were also jumps but I thought it is something
Vignesh should know. Maybe there is some fix for that too?
As Richard also noted, it would be nice if ti could let us know how to
get the delay values right. By trial and error is IMHO not the best
way.
For the testing I used 3.16.7.
