Yes, the hardware is out-of-spec. It uses the undefined low voltage OCR bit to achieve 1.8V SDIO voltage. By removing the MMC_VDD_165_195 restriction, commit 27cce39f555def6f5ebe7f03d69ccc44ab25f0b2 makes it possible for the hardware to work with unpatched kernels. Philip, David, Pierre - would you like to remove the MMC_VDD_165_195 restriction differently ? maybe to revive the MMC_CAP_VDD_165_195 host capability patch in some way (see http://www.mail-archive.com/linux-mmc@vger.kernel.org/msg00386.html) ? Thank you for the comments and help, Ohad. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
