2011-09-19mmc: Fix hangs related to insert/remove of cardsUlf Hansson
During a rescan operation mmc_attach(sd|mmc|sdio) functions are called. The error handling in these function can trigger a detach of the bus, which also meant a power off. This is not notified by the rescan operation which then continues to the next attach function. If a power off has been done, the framework must never send any new commands to the host driver, without first doing a new power up. This will most likely trigger any host driver to hang. Moving power off out of detach and instead handle power off separately when it is actually needed, solves the issue.

2011-09-19mmc: fix runtime PM with -ENOSYS suspend caseOhad Ben-Cohen
In the case where a driver returns -ENOSYS from its suspend handler to indicate that the device should be powered down over suspend, the remove routine of the driver was not being called, leading to lots of confusion during resume. The problem is that runtime PM is disabled during this process, and when we reach mmc_sdio_remove, calling the runtime PM functions here (validly) return errors, and this was causing us to skip the remove function. Fix this by ignoring the error value of pm_runtime_get_sync(), which can return valid errors. This also matches the behaviour of pci_device_remove().

2011-09-19mmc: core: Set non-default Drive Strength via platform hookPhilip Rakity
Non default Drive Strength cannot be set automatically. It is a function of the board design and only if there is a specific platform handler can it be set. The platform handler needs to take into account the board design. Pass to the platform code the necessary information. For example: The card and host controller may indicate they support HIGH and LOW drive strength. There is no way to know what should be chosen without specific board knowledge. Setting HIGH may lead to reflections and setting LOW may not suffice. There is no mechanism (like ethernet duplex or speed pulses) to determine what should be done automatically. If no platform handler is defined -- use the default value.

The way the request data is organized in the mmc queue struct, it only allows processing of one request at a time. This patch adds a new struct to hold mmc queue request data such as sg list, request, blk request and bounce buffers, and updates any functions depending on the mmc queue struct.

2011-09-19mmc: 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.

2011-09-19mmc: 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.

2011-09-19mmc: block: improve error recovery from command channel errorsRussell King - ARM Linux
Command channel errors fall into four classes: 1. The command was issued with the card in the wrong state 2. The command failed to be received by the card correctly 3. The cards response failed to be received by the host (CRC error) 4. The card failed to respond to the card For (1), in theory we should know that the card is in the correct state. However, a failed stop command (or other failure) may result in the card remaining in a data transfer state from the previous command. If we detect this condition, we try to recover by sending a stop command. For the initial commands (set block count and the read/write command) no data will have been transferred. All that we need deal with is retrying at this point. A failed stop command can be remedied as above. If we are unable to recover the card (eg, the card ignores our requests for status, or we don't recognise the error code) then we immediately fail the request.
