Subject: [PATCH v2 05/12] MIPS: DTS: CI20: fix PMU definitions for ACT8600
Date: Fri, 14 Feb 2020 17:10:17 +0100
Message-ID: <a583bde8332f8adb2ee97d775a36ef9dcf9b6419.1581696624.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1581696624.git.hns@goldelico.com>

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.

Fixes: 73f2b940474d ("MIPS: CI20: DTS: Add I2C nodes")
