From 627793e4ca4f511837de893545baf0e1b8174dc2 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Thu, 3 Jun 2021 08:42:30 +0300 Subject: regulator: bd9576 add FET ON-resistance for OCW BD9576MUF provides over-current protection and detection. Current is measured as voltage loss over external FET. Allow specifying FET's on resistance so current monitoring limits can be converted to voltages.
