ARM: dts: exynos: Fix regulators configuration on Peach Pi/Pit Chromebooks
Regulators, which are marked as 'on-in-suspend' seems to be critical for board operation, thus they must not be disabled anytime. This can be only assured by marking them as 'always-on', because otherwise some actions of their clients might result in turning them off. This patch restores suspend/resume operation on Peach-Pit Chromebook board. It partially reverts 'always-on' property removal done by the commit mentioned in the Fixes tag. Fixes: 665c441eea3d ("ARM: dts: exynos: Remove unneded always-on for regulators on Peach boards") Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Tested-by: Tomasz Figa <tfiga@chromium.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
