2010-05-27sdio: add new function for RAW (Read after Write) operationGrazvydas Ignotas2-0/+33
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. Android has similar patch for G1 in it's tree for the same reason: http://android.git.kernel.org/?p=kernel/common.git;a=commitdiff;h=74a47786f6ecbe6c1cf9fb15efe6a968451deb52 Signed-off-by: Grazvydas Ignotas <[email protected]> Acked-by: Kalle Valo <[email protected]> Cc: Dmitry Shmidt <[email protected]> Cc: <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2010-05-27mmc: remove the "state" argument to mmc_suspend_host()Matt Fleming23-26/+23
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.

2010-05-27mmc: OMAP HS-MMC: convert to dev_pm_opsKevin Hilman1-4/+11
Convert PM operations to use dev_pm_ops. This will facilitate the runtime PM coversion which will add to dev_pm_ops hooks. Note that dev_pm_ops version of the suspend hook no longer takes a 'state' argument. However, the MMC core function mmc_suspend_host() still takes a 'state' argument, but it is unused, so a dummy state variable was created to pass to the MMC core. In the future, the MMC core should be converted to drop this state argument and the rest of the MMC drivers could be easily converted to dev_pm_ops as well.

2010-05-27omap_hsmmc: improve interrupt synchronisationAdrian Hunter1-128/+134
The following changes were needed: - do not use in_interrupt() because it will not work with threaded interrupts In addition, the following improvements were made: - ensure DMA is unmapped only after the final DMA interrupt - ensure a request is completed only after the final DMA interrupt - disable controller interrupts when a request is not in progress - remove the spin-lock protecting the start of a new request from an unexpected interrupt because the locking was complicated and a 'req_in_progress' flag suffices (since the spin-lock only defers the unexpected interrupts anyway) - instead use the spin-lock to protect the MMC interrupt handler from the DMA interrupt handler - remove the semaphore preventing DMA from being started while the previous DMA is still in progress - the other changes make that impossible, so it is now a BUG_ON condition - ensure the controller interrupt status is clear before exiting the interrrupt handler In general, these changes make the code safer but do not fix any specific bugs so backporting is not necessary.

Unfortunately some architectures #define their read{b,w,l} and write{b,w,l} I/O accessors which makes the SDHCI I/O accessor functions of the same names subject to preprocessing.

2010-05-27davinci: mmc: pass number of SG segments as platform dataSudhakar Rajashekhara2-7/+20
On some platforms like DM355, the number of EDMA parameter slots available for EDMA_SLOT_ANY usage are few. In such cases, if MMC/SD uses 16 slots for each instance of MMC controller, then the number of slots available for other modules will be very few. By passing the number of EDMA slots to be used in MMC driver from platform data, EDMA slots available for other purposes can be controlled. Most of the platforms will not use this platform data variable. But on DM355, as the number of EDMA resources available is limited, the number of scatter- gather segments used inside the MMC driver can be 8 (passed as platform data) instead of 16. On DM355, when the number of scatter-gather segments was reduced to 8, I saw a performance difference of about 0.25-0.4 Mbytes/sec during write. Read performance variations were negligible.
