Subject: [PATCHv3 1/2] ARM: dts: socfpga: Fix SD card detect
Date: Tue, 21 Oct 2014 11:15:10 -0500 [thread overview]
Message-ID: <1413908111-28165-2-git-send-email-dinguyen@opensource.altera.com> (raw)
In-Reply-To: <1413908111-28165-1-git-send-email-dinguyen@opensource.altera.com>
From: Dinh Nguyen <dinguyen@opensource.altera.com>
Without this patch, the booting the SOCFPGA platform would hang at the
SDMMC driver loading. The issue, debugged by Doug Anderson, turned out
to be that the GPIO bank used by the SD card-detect was not set to
status="okay".
Suggested-by: Doug Anderson <dianders@chromium.org>

v3: Correctly degugged the issue to be a gpio node not having status="okay"
