Subject: [PATCH] arm/dt: Fix ventana SDHCI power-gpios
Date: Wed, 19 Oct 2011 10:53:57 -0600 [thread overview]
Message-ID: <1319043237-1474-1-git-send-email-swarren@nvidia.com> (raw)
Ventana uses the same SDHCI GPIOs as Seaboard; PI6 (70) is the power GPIO
for the SD port, and there is no power GPIO for the MMC chip.
Signed-off-by: Stephen Warren <swarren@nvidia.com>

Note: This bug doesn't actually prevent anything from working; since the
GPIO for sdhci at c8000400 was specified for sdhci at c8000600, it ended up
getting enabled anyway, and hence a card in sdhci at c8000400 would work fine.
Enabling GPIO 155/PT3 doesn't cause any harm on Ventana; it's not connected
to anything.
