Your change touches only the single board, so it should match the two. [Sai] : Noted. I will update in next patch As said before, your subject is too noisy, you can express this change with less words. Something like "...: Override Bluetooth vddio" completely covers the "what" of this patch, in 54 characters. [Sai]: I will decrease to less words > As IO regulator varies in different SC7280 platforms updating this > handler in individual platform bluetooth node. > "Bluetooth vddio in the CRD differs from that in the IDP, override it." Makes it clear what area is touched, what value is overriden and why it's overriden. [sai]: will update in next patch.
