2012-03-01mmc: queue: let host controllers specify maximum discard timeoutAdrian Hunter
Some host controllers will not operate without a hardware timeout that is limited in value. However large discards require large timeouts, so there needs to be a way to specify the maximum discard size. A host controller driver may now specify the maximum discard timeout possible so that max_discard_sectors can be calculated. However, for eMMC when the High Capacity Erase Group Size is not in use, the timeout calculation depends on clock rate which may change. For that case Preferred Erase Size is used instead.

2012-03-01mmc: core: add non-blocking mmc request functionPer Forlin
Previously there has only been one function mmc_wait_for_req() to start and wait for a request. This patch adds: * mmc_start_req() - starts a request wihtout waiting If there is on ongoing request wait for completion of that request and start the new one and return. Does not wait for the new command to complete. This patch also adds new function members in struct mmc_host_ops only called from core.c: * pre_req - asks the host driver to prepare for the next job * post_req - asks the host driver to clean up after a completed job The intention is to use pre_req() and post_req() to do cache maintenance while a request is active. pre_req() can be called while a request is active to minimize latency to start next job. post_req() can be used after the next job is started to clean up the request. This will minimize the host driver request end latency. post_req() is typically used before ending the block request and handing over the buffer to the block layer. Add a host-private member in mmc_data to be used by pre_req to mark the data. The host driver will then check this mark to see if the data is prepared or not.

2012-01-31clk: provide prepare/unprepare functionsRussell King
As discussed previously, there's the need on some platforms to run some parts of clk_enable() in contexts which can schedule. The solution which was agreed upon was to provide clk_prepare() and clk_unprepare() to contain this parts, while clk_enable() and clk_disable() perform the atomic part. This patch provides a common definition for clk_prepare() and clk_unprepare() in linux/clk.h, and provides an upgrade path for existing implementation and drivers: drivers can start using clk_prepare() and clk_unprepare() once this patch is merged without having to wait for platform support. Platforms can then start to provide these additional functions. Eventually, HAVE_CLK_PREPARE will be removed from the kernel, and everyone will have to provide these new APIs.

2012-01-31dmaengine: add DMA_TRANS_NONE to dma_transfer_directionShawn Guo
Before dma_transfer_direction was introduced to replace dma_data_direction, some dmaengine device uses DMA_NONE of dma_data_direction for some talk with its client drivers. The mxs-dma and its clients mxs-mmc and gpmi-nand are such case. This patch adds DMA_TRANS_NONE to dma_transfer_direction and migrate the DMA_NONE use in mxs-dma to it. It also fixes the compile warning below.

2012-01-31net: remove mm.h inclusion from netdevice.hAlexey Dobriyan
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
