Subject: [PATCH 5/6] ARM: dts: exynos: Add regulator suspend configuration to Arndale Octa board
Date: Thu, 20 Jun 2019 20:35:29 +0200 [thread overview]
Message-ID: <20190620183530.5386-5-krzk@kernel.org> (raw)
In-Reply-To: <20190620183530.5386-1-krzk@kernel.org>
Add the PMIC regulator suspend configuration to Arndale Octa board to
reduce power usage during suspend and keep necessary regulators on. The
configuration is based on vendor (Insignal) reference kernel.
This is purely for hardware description because board does not support
Suspend to RAM and the S2MPS11 driver does not support
"regulator-on-in-suspend" property.
