From: Andy Lutomirski Date: Sat, 1 Dec 2012 20:37:20 +0000 (-0800) Subject: PCI: Reduce Ricoh 0xe822 SD card reader base clock frequency to 50MHz X-Git-Tag: v3.7.2~19 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c9b184487ae4e1ec9c8d11b4ed1a23293fabb2ce;p=karo-tx-linux.git PCI: Reduce Ricoh 0xe822 SD card reader base clock frequency to 50MHz commit 812089e01b9f65f90fc8fc670d8cce72a0e01fbb upstream. Otherwise it fails like this on cards like the Transcend 16GB SDHC card: mmc0: new SDHC card at address b368 mmcblk0: mmc0:b368 SDC 15.0 GiB mmcblk0: error -110 sending status command, retrying mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0xb0 Tested on my Lenovo x200 laptop.
