Subject: [PATCH 2/2] ARM: dts: exynos4412-trats: Add suspend configuration for
max77686 regulators
Add suspend to RAM configuration for max77686 regulators. Some LDOs and
bucks are disabled. This reduces energy consumption during S2R,
approximately from 17 mA to 9 mA.
Additionally remove old and not supported bindings:
- regulator-mem-off
- regulator-mem-idle
- regulator-mem-on
The max77686 driver does not parse them and they are not documented
anywere.
Signed-off-by: Krzysztof Kozlowski <k.kozlowski@...sung.com>
