Subject: [PATCH v2 3/4] ARM: dts: exynos: Add regulator suspend configuration to Odroid XU3/XU4/HC1 family
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@...nel.org>
Tested-by: Marek Szyprowski <m.szyprowski@...sung.com>
---
Tested on XU3 and HC1 with SD card.
---
Changes since v1:
1. Add Marek's tag.
