Subject: [PATCHv3 0/2] ARM: dts: socfpga: fix booting with SD/MMC
Date: Tue, 21 Oct 2014 11:15:09 -0500 [thread overview]
Message-ID: <1413908111-28165-1-git-send-email-dinguyen@opensource.altera.com> (raw)
From: Dinh Nguyen <dinguyen@opensource.altera.com>
The SOCFPGA dev kit was hanging during bootup on the SD/MMC driver loading.
The first patch fixes the booting and the 2nd patch adds a regulator node
for the SD/MMC driver to use.
v3 diff(s): Thanks to Doug Anderson, the real issue was that the GPIO bank used
by cd-gpios did not have status="okay" in the node. This cause the GPIO to not
get probed correctly.
In fact, prior to patch 3cf890fc42b "mmc: dw_mmc: Pass back errors from
mmc_of_parse()", the error was being masked, so it was not being detected.
v2 diff(s): Patch 2/2 ARM: dts: socfpga: Add a 3.3V fixed regulator node
- Move the regulator nodes to their respective board dts file and
correctly rename the regulator to match the schematic
