Right, when i have debugged, this commit 97f659a2e (mmc: dw_mmc: prevent to set the wrong value) is problem. If Ulf can revert it, otherwise i needs to modify the dts file of arndale baord. In future, I will fix more exactly. Sorry for this. When i have checked, Before reverting, [ 2.757696] mmc_host mmc0: vqmmc not available.(Skip the switching voltage) [ 2.757713] mmc0: error -22 whilst initialising MMC card After reverted, [ 2.480755] mmc0: new DDR MMC card at address 0001 [ 2.481723] mmcblk0: mmc0:0001 SDW16G 14.7 GiB [ 2.482218] mmcblk0boot0: mmc0:0001 SDW16G partition 1 4.00 MiB [ 2.482681] mmcblk0boot1: mmc0:0001 SDW16G partition 2 4.00 MiB [ 2.483345] mmcblk0rpmb: mmc0:0001 SDW16G partition 3 4.00 MiB [ 2.486493] mmcblk0: p1 p2 p3 p4 < p5 p6 > How about? revert? otherwise I will send to fix the patch. I will accept Ulf's opinion. Sorry for this, again.
