From: Dinh Nguyen <redacted> 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.

This doesn't look right to me. What was the error that was passed back? I think your change has the same net effect as just deleting the "cd-gpios" line. ...or is there some code somewhere that is parsing the "cd" property.
