From e8d87a0b822d4b3d9a94a5da915f93aa1b674c93 Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" Date: Fri, 6 Mar 2020 18:27:58 +0100 Subject: [PATCH] MIPS: DTS: CI20: fix PMU definitions for ACT8600 There is a ACT8600 on the CI20 board and the bindings of the ACT8865 driver have changed without updating the CI20 device tree. Therefore the PMU can not be probed successfully and is running in power-on reset state. Fix DT to match the latest act8865-regulator bindings.
