Subject: [PATCH 1/3] ARM: dts: Mark SDIO as non-removable in exynos5800-peach-pi
Date: Thu, 15 Oct 2015 12:55:28 +0200 [thread overview]
Message-ID: <1444906530-25048-2-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1444906530-25048-1-git-send-email-javier@osg.samsung.com>
The Exynos5800 Peach Pi Chromebook has a Marvell WiFi SDIO chip which
can't neither be removed nor be detected. But the node isn't marked
as non-removable and instead has the broken-cd DT property.
This causes the device to be removed when the system enters into a
suspend state and the following warnings is shown after a resume:
[ 181.944636] mmc2: error -2 during resume (card was removed?)
