sdio: add new function for RAW (Read after Write) operation 2010-05-27T16:12:40+00:00 Grazvydas Ignotas notasas@gmail.com 2010-05-26T21:42:09+00:00 6c1f716e8154ee9315534782b9b1eedea0559a24 SDIO specification allows RAW (Read after Write) operation using IO_RW_DIRECT command (CMD52) by setting the RAW bit. This operation is similar to ordinary read/write commands, except that both write and read are performed using single command/response pair. The Linux SDIO layer already supports this internaly, only external function is missing for drivers to make use, which is added by this patch. This type of command is required to implement proper power save mode support in wl1251 wifi driver.

mmc: remove the "state" argument to mmc_suspend_host() 2010-05-27T16:12:40+00:00 Matt Fleming matt@console-pimps.org 2010-05-26T21:42:08+00:00 1a13f8fa76c880be41d6b1e6a2b44404bcbfdf9e Even though many mmc host drivers pass a pm_message_t argument to mmc_suspend_host() that argument isn't used the by MMC core. As host drivers are converted to dev_pm_ops they'll have to construct pm_message_t's (as they won't be passed by the PM subsystem any more) just to appease the mmc suspend interface. We might as well just delete the unused paramter.
