From 3aca6ecdab44b30e812001ab4de19b79001a3fbd Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 20 Nov 2021 16:53:12 +0100 Subject: power: supply: ab8500: Sink current tables into charger code The two tables for input and output current translation from register values does not need to be passed around from the battery manager data. Just push it down into the charger code where it is used, like other tables in that code.
