From 3a003baeec246f604ed1d2e0087560d7f15edcc6 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 17 Jul 2015 14:41:54 -0700 Subject: regulator: Add over current protection (OCP) support Some regulators can automatically shut down when they detect an over current event. Add an op (set_over_current_protection) and a DT property + constraint to support this capability.
