| Subject: ARM: dts: exynos: Fix regulators configuration on Peach Pi/Pit |
| Chromebooks |
| |
| From: Marek Szyprowski <m.szyprowski@samsung.com> |
| |
| [ Upstream commit f8f3b7fc21b1cb59385b780acd9b9a26d04cb7b2 ] |
| |
| 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. |
