Subject: [PATCH 6/6] ARM: dts: exynos: Add regulator suspend configuration to Odroid XU3/XU4/HC1 family
Date: Thu, 20 Jun 2019 20:35:30 +0200	[thread overview]
Message-ID: <20190620183530.5386-6-krzk@kernel.org> (raw)
In-Reply-To: <20190620183530.5386-1-krzk@kernel.org>

Add the PMIC regulator suspend configuration to entire Odroid
XU3/XU4/HC1 family of boards to reduce power usage during suspend.  The
configuration is based on vendor (Hardkernel) reference kernel.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
