Subject: [PATCH 1/2] ARM: dts: socfpga: Fix SD card detect
Date: Thu, 16 Oct 2014 16:03:32 -0500 [thread overview]
Message-ID: <1413493413-8041-2-git-send-email-dinguyen@opensource.altera.com> (raw)
In-Reply-To: <1413493413-8041-1-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. There were 2 patches that caused this to happen:
- Patch 9795a846e10 "mmc: dw_mmc: remove dw_mci_of_cd_gpio/wp_gpio()" removed
looking for "cd-gpios", since mmc_of_parse was getting called.
- Patch 3cf890fc42b "mmc: dw_mmc: Pass back errors from mmc_of_parse()" would
hang the system at the SDMMC driver loading.
This patch will fix booting with SDMMC enabled on SOCFPGA dev kit.
