2010-07-05of: refactor of_modalias_node() and remove explicit match table.Grant Likely
This patch tightens up the behaviour of of_modalias_node() to be more predicatable and to eliminate the explicit of_modalias_tablep[] that is currently used to override the first entry in the compatible list of a device. The override table was needed originally because spi and i2c drivers had no way to do of-style matching. Now that all devices can have an of_node pointer, and all drivers can have an of_match_table, the explicit override table is no longer needed because each driver can specify its own OF-style match data. The mpc8349emitx-mcu driver is modified to explicitly specify the correct device to bind against. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2010-06-04omap: remove BUG_ON for disabled interruptsCory Maccarrone
Remove a BUG_ON for when interrupts are disabled during an MMC request. During boot, interrupts can be disabled when a request is made, causing this bug to be triggered. In reality, there's no reason this should halt the kernel, as the driver has proved reliable in spite of disabled interrupts, and additionally, there's nothing in this code that would require interrupts to be enabled. The only setup I've managed to make it trigger on is on the HTC Herald during bootup when the driver is built into the kernel (mostly because that's all I have). I believe it's related to the fact that on bootup I get many timeout errors on "CMD5" while initializing the card. Each CMD5 timeout triggers that bug (I changed it to a WARN_ON to get it to boot in) due to the fact that part of the timeout code involves sending the request again. With interrupts turned off, that BUG would be triggered.

2010-05-27sdio: add new function for RAW (Read after Write) operationGrazvydas Ignotas
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 <notasas@gmail.com> Acked-by: Kalle Valo <kalle.valo@iki.fi> Cc: Dmitry Shmidt <dimitrysh@google.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-05-27mmc: remove the "state" argument to mmc_suspend_host()Matt Fleming
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 Hilman
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 Hunter
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.

Enable high speed support for atmel-mci driver. This support is dependent of the revision of the IP and, of course, the capacity of the SD card used.

2010-05-27mmc: sd: clean up redundant memsetMark Asselstine
The clearing of mrq via a memset at the top of the for loop in mmc_wait_for_app_cmd() is not required as mrq is not used and there is another clearing of mrq just below. We remove the first memset since if the initial tests in the for loop fail the memset is not required.

2010-05-27davinci: mmc: updates to suspend/resume implementationChaithrika U S
Improve the suspend and resume callbacks in DaVinci MMC host controller driver. Modify the reset status of the contorller and clock during suspend and resume. Also migrate the power management callbacks from platform driver to dev_pm_ops structure. Tested on DA850/OMAP-L138 EVM.

2010-05-27sdhci-pltfm: do not print errors in case of an extended iomem sizeAnton Vorontsov
Some hosts have an extended SDHCI iomem size, so the driver should only print errors if the iomem size is less than 0x100.

2010-05-27sdhci: implement CAP_CLOCK_BASE_BROKEN quirkAnton Vorontsov
Some hosts (e.g. as found in CNS3xxx SOCs) report wrong value in CLOCK_BASE capability field, and currently there is no way to force the SDHCI core to use the platform-provided base clock value. This patch implements CAP_CLOCK_BASE_BROKEN quirk. When enabled, the SDHCI core will always use base clock frequency provided by the platform.

2010-05-27mmc-omap: add support for 16-bit and 32-bit registersMarek Belisko
The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring a modification of the register addresses in the mmc-omap driver. To resolve this, a bit shift is performed on base register addresses, either by 1 or 2 bits depending on the CPU in use. This yields the correct registers for each CPU.

2010-05-27davinci: mmc: pass number of SG segments as platform dataSudhakar Rajashekhara
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.
