Downstream doesn't do val |= readl() in the inrush-current-mitigation
case
I have checked you are right, thanks. 1_8 reset sequence have it but
1_8_inrush_current have not.
As i understanding from downstream it should be handled in both for
loop, i could add an if for
handle this or implement 1_8_inrush_current reset separately. Which one
would be the preferred?
