regulator: Policy for setting current limits

["Heiko Stübner" <heiko@sntech.de>]

Hi,

I hit a problem when setting a current limit and am not sure whose fault it is 
(i.e. which component to change). Therefore I'd appreciate a pointer in the 
right direction.

After the recent changes the gpio-regulator always selects the minimal value 
to set. The gpio-vbus driver sets it's current limits as 0 - x mA (x = 100, 
500). Therefore if 500mA are the upper limit but the regulator also supports 
lower values, these lower values always get selected (100mA in my case).
In contrast pda_power sets the target current as both lower and upper limit.

So the question is, what is the correct way to handle this:

(a) let the gpio-regulator select the max current (in contrast to the minimum 
voltage)
(b) change gpio-vbus to also use the target current as min and max value
(c) something else


Thanks
Heiko
