Some capacity estimation computations require higher accuracy. Add

That sounds useful.
+int power_supply_ocv2dcap_simple(struct power_supply_battery_ocv_table *table,
+ int table_len, int ocv)
+{
+ int i, cap, tmp;
Why a whole new function? Just rename the original power_supply_ocv2cap_simple()
to power_supply_ocv2dcap_simple and patch it to return the finegrained value,
then add a wrapper that use that function but drops it down by one order
of magnitude.
/me feels slightly stupid.
I wonder ehy you had to explain this to me :) Well, thanks and agreed!
+int power_supply_batinfo_ocv2dcap(struct power_supply_battery_info *info,
+ int ocv, int temp)
Same with this, saves a lot of code!
(Also will use my new interpolation routines since you refactor
on top of that.)
yup. I think this will be _much_ cleaner. I need to revise also the IC
driver patches because I think I implemented something like your
interpolation routines there too. So - thanks.
Best Regards
Matti
