PCI rescan needed for MMC reader to become usable

2013-01-03 Thread Cristian Rodríguez
Hi: My laptop's card reader (dell xps 15z uses driver jmb38x_ms, kernel 3.8-rc2 or older no difference) does nothing unless: a) An SD card is plugged into the slot before powering the machine on. b) I plug the card and run echo 1 > /sys/bus/pci/rescan then the device appears [ 2154.277991]

[PATCH v3 3/3] mmc: core: Fixup signal voltage switch

2013-01-03 Thread Johan Rudholm
When switching SD and SDIO cards from 3.3V to 1.8V signal levels, the clock should be gated for 5 ms during the step. After enabling the clock, the host should wait for at least 1 ms before checking for failure. Failure by the card to switch is indicated by dat[0:3] being pulled low. The host shoul

This patch series attempts to make the 1.8V signal voltage switch required for UHS mode work according to the SD specification. These patches have been tested with a couple of UHS SD cards, one of which sometimes requires up to five power cycles before it accepts the signal voltage switch. The pat
