Subject: [PATCH 4/5] ARM: dts: rockchip: vcc33_ccd off in suspend for rk3288-veyron-chromebook
Date: Thu, 11 Apr 2019 16:21:56 -0700 [thread overview]
Message-ID: <20190411232157.55125-4-dianders@chromium.org> (raw)
In-Reply-To: <20190411232157.55125-1-dianders@chromium.org>
As per my comments when the device tree for rk3288-veyron-chromebook
first landed:
> Technically I think vcc33_ccd can be off since we have

> more solid.
It's probably about time to do it right.
